Reducing Phosphorus to Wisconsin Waters – Another Tool in the Toolkit

Posted on July 2, 2014 by Linda Bochert

Imagine a nutrient reduction program that achieves financially manageable point source reductions while generating new cash for nonpoint source reductions, has bi-partisan support and requires no new state regulatory or fee programs.  Not possible you say?  Meet the Wisconsin Clean Waters, Healthy Economy Act, now codified at Wis. Stat. s. 283.16.

 In prior postings, I have described Wisconsin’s phosphorus reduction rule, including its compliance options of water quality trading and adaptive management. These are innovative alternatives to traditional construction but, unfortunately, not viable for all dischargers.

Now Wisconsin has another tool:  a multi-discharger variance, based on a finding of statewide social and economic impact, available to dischargers that cannot meet the water quality based effluent limitation (WQBEL) for phosphorus without a major facility upgrade.   Under the variance, a point source will still be required to decrease its phosphorus discharge -- meeting interim limitations of 0.8 mg/L, 0.6 mg/L, 0.5 mg/L, and the final WQBEL over four WPDES permit terms; and while doing so will make payments to the counties within its basin, providing cost-share dollars for nonpoint source phosphorus reductions.  At $50/pound for the difference between the actual pounds of phosphorus discharged and the target value of 0.2 mg/L, this is expected to generate real money -- which the counties will use to implement existing, but seriously underfunded, nonpoint source reduction programs.

Because point sources have installed treatment and reduced their phosphorus discharges by 90% or more to meet Wisconsin’s prior technology-based limit of 1.0 mg/L, the remaining primary contributors of phosphorus to our waters are nonpoint sources.  Yet getting funding for nonpoint source controls has been an ongoing, and largely unsuccessful, effort.  For context, the Green Bay Metropolitan Sewerage District (GBMSD) currently removes about 95% of the phosphorus it receives; while the wastewater it discharges accounts for less than 3% of the total phosphorus to the lower Green Bay.  With an investment of $200 million in capital improvements GBMSD could increase its removal to 98% -- a reduction of less than 2% of the total phosphorus load to the bay.   Redirecting significant dollars to nonpoint source programs should be a game-changer.

The Wisconsin Department of Natural Resources (WDNR) has been reissuing WPDES permits with phosphorus WQBELs and compliance schedules based on the phosphorus reduction rule that went into effect in December 2010.  The variance law went into effect on April 25, 2014, but won’t become available to WPDES permit holders until approved by USEPA.  The rule package is expected to be sent to USEPA for approval in January 2015, once the statewide economic impact analysis is completed. 

We have an opportunity for creative and meaningful point source and nonpoint source participation in reducing phosphorus discharges to our waters.  But time is of the essence.  Note to USEPA:  there is much to like here – please don’t let the moment pass us by.

EPA’s RDA Math: 3 + 9 ≠ 1

Posted on June 20, 2014 by David Van Slyke

In a surprising turn of events, on March 12, 2014 EPA Regions 1, 3 and 9 each simultaneously but separately responded, and each in a somewhat different way, to three virtually identical NGO petitions asking those Regions to use their Clean Water Act (“CWA”) Residual Designation Authority (“RDA”) to require that stormwater discharges from impervious surfaces at existing commercial, industrial and institutional (“CII”) sites be permitted under CWA Section 402.  The three petitions were filed in July 2013 by several different and somewhat overlapping consortia of environmental organizations.

The three Regions’ responses were all signed by their respective Regional administrators, each was worded differently, and each included a somewhat similar -- yet somewhat different --explanatory enclosure that detailed the basis of each respective Region’s response.

EPA Region 3’s response is a flat out denial of the petition, citing existing tools and programs already in place to address stormwater pollution (e.g., MS4 permits, TMDL implementation and strong state programs).  The enclosure with the Regional Administrator’s letter denying the petition also states that “Region III declines to begin a process for categorical designation of discharges from CII sites to impaired waters since … the data supplied by the Petitioners to support the exercise of RDA is insufficient.”  The enclosure does note that if the existing programs ultimately do not meet their objectives, alternate tools, including RDA, will need to be considered.

Similarly, EPA Region 9’s response “declines to make a Region-wide designation of the sources” in the petition specific to Region 9.  That response also concludes in the enclosure that “we currently have insufficient information to support a Region-wide designation” of the CII sites specified in the petition, “that effective programs are already in place that address the majority of the sites identified in the petition,” and that the Region will keep designation in their toolbag as they “continue to evaluate currently unregulated sources of stormwater runoff.”

However, Region 1’s response states that it “is neither granting the petition … nor is it denying the petition.”  Instead, the Region is going to evaluate individual watersheds in its six states to look at the nature and extent of impairment caused by stormwater, and then “to determine whether and the extent to which exercise of RDA is appropriate.”

Given the identical language in certain portions of all three of the Regional response enclosures (e.g., Statutory and Regulatory Background; Petition Review Criteria), it is clear that EPA Headquarters was in the thick of the discussions regarding the responses to these three RDA petitions.  However, the apparent autonomy afforded each Region in determining how to deal with the issue is remarkable, and the discussions ultimately may have centered (as they often do at EPA HQ) on resource allocations nationally and within each Region. 

The responses of Regions 3 and 9 imply that their current respective paths, with time, will get results without diverting resources.  EPA Region 1 appears to more fully embrace RDA as a near-term viable tool to more aggressively control stormwater runoff from CII sites.  Apparently, the New England regulators’ successful experience with the Long Creek Watershed RDA and their efforts relative to the RDA process for the Charles River has only whetted their appetite for further candidate areas at which to employ this model to address impaired stormwater. 

Whether the NGOs will seek judicial relief from the denial of their Petitions, whether the states in the USA’s upper right hand corner will be supportive of EPA New England’s continued utilization of this tool, as well as how this issue ultimately will be played by EPA HQ, is fuzzy math.

A SWING AND A MISS -- The First Reported Challenge to Water Quality Trading is Dismissed for Lack of Standing

Posted on January 24, 2014 by Allan Gates

EPA has touted water quality trading for more than a decade as a viable tool for combating water pollution, particularly pollution due to excess nutrients and sediment.  But the Clean Water Act contains no express authority for water quality trading or offsets, and some environmental groups view trading as a “license to pollute” that violates the Clean Water Act’s promise to eliminate the discharge of pollutants into waters of the United States.

Last month a federal district court issued a final ruling in the first reported challenge to the legality of water quality trading.  The court dismissed the action without reaching the legality of water quality trading.   Instead, the court held that the plaintiff environmental groups (Food and Water Watch and Friends of the Earth) lacked standing and that EPA’s  “authorization” of trading in the Chesapeake Bay TMDL was not a final agency action.  Food and Water Watch v. EPA, No. 1:12-cv-01639 (D.D.C. decided December 13, 2013).

Although the court’s decision did not address the substantive legality of water quality trading, the case still presents four interesting aspects that may prove instructive on what to expect in future challenges.

First, environmental groups split over the question of joining the challenge to water quality trading.  It is widely rumored that Food and Water Watch actively solicited support from environmental groups involved in Chesapeake Bay issue but met with stiff resistance. It appears that the other environmental groups’ support for the Chesapeake Bay TMDL overrode any interest they might otherwise have had in supporting a challenge to the legality of water quality trading.

Second, the defense of water quality trading made for strange bedfellows.  Three parties intervened as defendants.  One was a group representing municipal point source dischargers who support the Chesapeake Bay TMDL (National Association of Clean Water Agencies).  Two were non point source groups who are actively challenging the legality of the Chesapeake Bay TMDL in another case (American Farm Bureau and National Association of Home Builders).  The non-point source representatives argued that the trading component of the Bay TMDL would be important and valuable to their members if their challenge to the validity of the Bay TMDL in the other case was unsuccessful.

Third, the court’s decision on standing, ripeness, and the question of final agency action suggests it may be difficult to litigate the basic legality of water quality trading until a program is fully established and permits allowing credit for trades are issued.  EPA argued successfully that no actual or imminent injury to the plaintiffs was caused by the Chesapeake Bay TMDL’s express reference to trading as a means for meeting the waste load allocations.  According to this argument, the TMDL did not compel any trades; it simply acknowledged that states in the Chesapeake Bay watershed might use trading as a tool in developing permits that implement the TMDL.  Carrying this argument to its logical conclusion, one could envision the possibility that there would be no basis for private party standing to challenge the legality of a trading program until after a stream has been listed as impaired, a TMDL has been performed, a trading program has been established, and permits have been issued allowing credits for trades within the program.  Litigating the legality of water quality trading at such a late stage would presumably face a significant task in unwinding the momentum of such a fully developed administrative structure.

Fourth, given the success of EPA’s standing and ripeness arguments, it seems unlikely that there will be any definitive judicial ruling on the legality of water quality trading any time soon.  The partisan division in Congress makes clarifying legislative action even less likely.  As a consequence, EPA’s success in defending against the Food and Water Watch lawsuit may have the ironic result of postponing the day when states and permit holders will have a clear and definitive answer regarding the basic legality of water quality trading.

USEPA Proposes Revisions to the Water Quality Standards Program Under the Clean Water Act

Posted on October 23, 2013 by Kevin Beaton

On September 4, 2013 EPA published proposed changes to its Water Quality Standards Rule at 40 CFR Part 131 (WQS Rule).  The proposal is styled “regulatory clarifications” but the proposal represents the most significant changes made to the WQS Rule in some thirty years.  The WQS Rule currently sets forth the minimum conditions that must be met in each State’s or Tribe’s water quality standards before EPA can approve them under the Clean Water Act (CWA).  Increasingly over the years, state water quality standard decisions have been the driver behind required stringent permit limits in NPDES Permits, TMDLs for impaired waters and lawsuits against EPA.  The proposed rule is mostly an attempt to codify exciting EPA guidance and practices to ensure national consistency and “transparency.”  Many of the proposed changes were generally discussed in EPA’s Advance Notice of Proposed Rule Making (ANPRM) on water quality standards published in 1998 and many come from the Great Lakes Water Quality Guidance at 40 CFR Part 132.

First EPA is proposing to amend the use attainability analysis (UAA) requirements found in the current rule to now require a state or Tribe to identify the highest attainable use (HAU) and the water quality criteria to protect the HAU in any UAA.  A UAA is a structured analysis a State or Tribe can undertake to attempt to demonstrate to EPA that the so called “fishable and swimmable” uses required under the CWA are not attainable based on a number of factors.  These factors include low flows, natural or physical conditions, human caused conditions which cannot be remedied, dams, or because controls to achieve attainment would be too expensive.  At least in the Northwest, EPA have been very reluctant to approve UAAs because the agency has a “rebuttable presumption” that fishable uses and swimmable uses are attainable (some might call it an irrebuttable presumption) and implicitly that it is never too expensive to remedy water quality problems.  Requiring states and Tribes to also adopt a new HAU in connection with a UAA along with associated criteria may make the UAA an even less viable CWA off-ramp.

Speaking of off-ramps, the proposed rule also sets forth the conditions under which a state or Tribe can adopt “variances” to water quality standards for individual or groups of NPDES permittees.  Variances are merely referenced in the current WQS Rule and have been viewed as a “UAA lite.”  Variances are codified in water quality standards (subject to approval by EPA) and allow individual dischargers or groups of NPDES Permits to temporarily exceed water quality based effluent limits based on the same factors which justify a UAA.  EPA articulates in the proposal that it believes variances have been underutilized and therefore sets forth the conditions which the Agency will grant variances for an individual or groups of NPDES permittees.  (e.g. Demonstrate temporary unattainability, maximum timeline of 10 years and protect the HAU during the variance.)  Whether the proposal will lead to more variances may be doubtful.  EPA has typically been unwilling to approve variances for industrial or commercial dischargers (although they are more flexible with municipalities) because pollution controls to meet WQS are seemingly never too expensive.

As my colleague Patricia Barmeyer notes in her recent post, the proposed rule also proposes changes to antidegradation implementation procedures that are somewhat consistent with current practices and guidance by providing some flexibility in how states protect high quality waters and a specific requirement that states must first require dischargers to implement “practicable” pollution controls that minimize or eliminate any degradation to high quality before allowing the discharge.  “Practicable” is not defined but if this term is implemented in the same way as proving economic hardship in a UAA or variance then new and increased discharges could be subject to additional (and expensive) hurdles in going through antidegradation reviews.  Finally, the proposed rule addresses compliance schedules in NPDES permits consistent with current practice and specifies the conditions under which the EPA Administrator will make determinations that a water quality standard does not meet the requirements of the CWA.  Comments on the proposed rule are due on December 3, 2013 (unless an extension is granted).

Court Upholds Multi-State Chesapeake TMDL

Posted on September 25, 2013 by Ridgway Hall

On September 13, in a 99 page decision, the U.S. District Court for the Middle District of Pennsylvania upheld EPA’s multi-state Clean Water Act Total Maximum Daily Load (“TMDL”) for the Chesapeake Bay and its tributaries against a broad range of challenges brought by the American Farm Bureau Federation and six other farm industry trade associations. Six environmental organizations led by the Chesapeake Bay Foundation, plus four municipal water associations led by the National Association of Clean Water Agencies, intervened in support of EPA.

The Chesapeake Bay TMDL is not the first to cover multiple states, but it is by far the largest, covering 64,000 square miles in Maryland, Virginia, Delaware, Pennsylvania, West Virginia, New York and the District of Columbia.  It requires substantial reductions of nitrogen (25%), phosphorus (24%) and sediment (20%) by 2025 to  meet water quality standards.  Because of the interstate nature of the long-standing pollution problems, after more than two decades of collaborative but unsuccessful efforts, the states agreed in 2007 that EPA should develop the TMDL. It was issued in 2010 and included allocations for each of 92 tidal segments which, after consultation with the states, were further allocated among states, watersheds and sectors (such as agriculture, wastewater, stormwater, etc). During the process, each state developed its own Watershed Implementation Plan (“WIP”), specifying  wasteload allocations (“WLA’s”) for point sources, load allocations (“LAs”) for nonpoint sources, and identifying the regulations, programs and resources that would be used to achieve the required reductions. For more on this TMDL see "EPA Issues Biggest TMDL Ever for Chesapeake Bay Watershed" and ELI Environmental ForumThe Chesapeake Bay TMDL” (May/June 2011). 

The plaintiffs alleged that (1) the TMDL was an unauthorized “implementation” of  allocations by EPA, (2) requiring WIPs exceeded EPA’s authority, (3) EPA’s use of watershed and related models in setting the allocations was an abuse of discretion, and (4) there was insufficient public notice.  In addressing these challenges, the court first held (as several others have) that a TMDL is not self-implementing, but is an “informational tool”, developed collaboratively by EPA and the states under CWA Section 303(d), and implemented primarily by the states.

Turning to the merits, the court upheld EPA’s definition of a TMDL for a waterbody or segment as the sum of all WLAs and LAs plus natural background.  It also upheld  EPA’s authority to establish a multi-state TMDL,  when the affected states either fail to do so or ask EPA to do it (both occurred here), including limitations on sources in upstream states to achieve compliance with water quality standards in downstream states. It held that EPA’s “holistic” or “watershed-wide approach” was consistent with the broad national goals of the CWA to “restore … our Nation’s waters.” In reaching this result the court emphasized the collaborative efforts of the Bay states and EPA starting in 1983 to address the problems of interstate pollution, transported by rivers and tides, and their consensus that an EPA-led multistate effort was needed.

The court further held that the WIPs – new tools in the TMDL context – were authorized as part of the “continuing planning process” under CWA Section 303(e). This process is initiated by the states to achieve water quality goals, and is subject to review and approval by EPA. Because EPA had advised the states in letters what it expected in terms of general content and specificity in the WIPs, but left the details to the states, the court held EPA did not exceed its authority. The court also relied on CWA Section 117(g) - a Chesapeake Bay-specific provision - requiring EPA to “ensure that management plans are developed and implementation is begun by [all the affected states] to achieve and maintain…” the applicable water quality goals.

The plaintiffs also challenged EPA’s requirement that each WIP contain “reasonable assurances” of timely and effective implementation, and EPA’s use of “backstop” allocations where EPA determined that a WIP provision was deficient.  “Backstops” involved requiring NPDES permits from previously unregulated sources. The court held that EPA could properly require “reasonable assurance” under CWA 303(d)(1), which requires a TMDL must be “established at a level necessary to implement the applicable water quality standards.”  The court upheld “backstops”, which were only used in 3 instances, as a reasonable exercise of EPA’s authority under CWA 303(d)(2) to ensure that the contents of the TMDL are designed to achieve the applicable water quality goals.

The court upheld EPA’s use of models as scientifically supported and within EPA’s discretion.  It rejected the challenge to adequate notice and opportunity for public participation since (1) a 45 day public comment period had been provided, (2) there had been hundreds of public meetings during the more than 10 year development of the TMDL, and (3) plaintiffs showed no prejudice from the fact that some details of the modeling were not available until after the comment period.

The court held that TMDL establishment and implementation involves “cooperative federalism” between the states and EPA, and that the Chesapeake Bay TMDL properly reflects the shared responsibilities and necessary interactions, despite some bumps along the road. While EPA exerted strong leadership, the court held that it did not unlawfully usurp the states’ implementation functions. The court noted  the preserved authority of the states to implement nutrient trading and offsets, and to set or revise source-specific loading allocations.  In conclusion, there is a lot of thoughtful analysis, as well as precedent, in this decision, which makes it an excellent resource for CWA practitioners.

“Whenever”: EPA’s Continuing Power to Withdraw Dredge-and-Fill Permits

Posted on May 1, 2013 by Lisa Heinzerling

On April 23, a panel of the D.C. Circuit unanimously held in Mingo Logan Coal Co. v. EPA that the Clean Water Act gives EPA the authority to withdraw permits previously granted under section 404 of the Act.  The case emerged from EPA’s determination that the discharge of mining waste from the Spruce No. 1 mine in West Virginia into certain streams and tributaries would have an unacceptable adverse effect on environmental resources.  Based on this determination, EPA withdrew the Army Corps of Engineers’ prior specification of these streams and tributaries as disposal sites for the waste from mountaintop removal.

Several features of the case are striking.  First, the decision has obvious – and obviously important – implications for the ongoing debate over mountaintop removal and its irredeemable environmental impacts.  No longer can the argument be made that a permit, once issued, gives the permittee the power, in perpetuity, to blast the tops off of mountains and dump them into streams.

Second, the decision rested, for the most part, on a single word: “whenever.”  The Clean Water Act states that the Administrator of the EPA may withdraw the specification of a disposal site for dredge-and-fill material “whenever” she determines that it will have an “unacceptable adverse impact” on certain environmental resources.  The court took Congress, literally, at its word, and held that “whenever” means whenever – that is, even if EPA finds unacceptable adverse impacts after a permit has issued, the agency has the authority to pull the permit.

Third, as if to make certain its own holding is unambiguous, too, the court five times stated that the Clean Water Act unambiguously authorizes EPA to withdraw permits after they are issued.  EPA’s current interpretation of the Act is thus not changeable by a future administration.

Should permittees fear that “whenever” will become wherever?  It is worth remembering that EPA’s decision on the Spruce No. 1 mine was the first time EPA had – ever! – withdrawn a previously issued permit, in the 40-year history of the Clean Water Act.  Whether EPA will be emboldened by this decision, or will continue to mostly allow existing permits to stand, remains to be seen.

Court Rules EPA Cannot Set TMDL For Stormwater

Posted on April 30, 2013 by Ridgway Hall

On January 3, 2013, the District Court for the Eastern District of Virginia ruled that EPA lacks the statutory authority to set a Clean Water Act (“CWA”) total maximum daily load (“TMDL”) for “stormwater flow rates” as a surrogate for sediment deposition. Virginia Dep’t of Transportation et al v EPA et al.  EPA has decided not to appeal.  The case has received national attention because of its implications for other TMDLs that use surrogates. This article will discuss the decision and its significance for the TMDL and water quality regulatory regime.

The relevant statutory framework is CWA Section 303, under which each state establishes water quality standards for waters within its boundaries.  These consist of a designated use (trout fishing, contact recreation, etc.) and numerical or narrative “water quality criteria” necessary to support that use.  For “impaired waters” where the criteria are not being met, the state must set a TMDL (think “pollution budget”) for each pollutant for which the criteria are exceeded, and implement a “planning process” leading to achievement.  Where the state fails to act, or sets a TMDL which EPA regards as insufficient, CWA Section 303(d)(2) directs EPA to set the TMDL.

Accotink Creek is a 25 mile tributary to the Potomac River in Virginia, in which the benthic organisms were impaired, primarily because of sediment deposited by stormwater running off impervious urban and suburban areas.  In April 2011, after Virginia failed to set a TMDL, EPA set one which limited the flow rate of stormwater into Accotink Creek to 681.8 cu ft/ acre-day.  The court said that the parties agreed that “sediment is a pollutant, and that stormwater is not” (Slip op. 3). While EPA’s brief contains a fallback argument that stormwater can be viewed as a “pollutant”, it did not dispute that stormwater flow was being used as a surrogate for sediment.  Thus the question addressed by the court was whether EPA has the statutory authority to set a TMDL for a “surrogate” which is not itself a “pollutant”. 

EPA has used surrogates in a number of circumstances where, in its view, the surrogate would provide appropriate reduction of pollutants, and would be either easier to measure or provide other benefits (such as, in this case, reduction of stream bank scouring caused by heavy stormwater discharges), or both. The court rejected EPA’s argument that since the CWA does not expressly address the use of surrogates, EPA’s use of them should be upheld as reasonable “gap-filling”, consistent with the broad remedial objectives of the CWA, and entitled to substantial Chevron step 2 deference. The court held instead that because the CWA instructed EPA to set TMDLs for “pollutants”, not “surrogates”, the statute was clear.  The court distinguished EPA’s use of surrogates in this case from other instances  in which surrogates have been used under other CWA provisions (notably Sections 301, 304 and 402) where EPA appears to have greater latitude.

EPA and states have used stormwater surrogates in TMDLs in Connecticut, Missouri and North Carolina. They have also used other types of surrogates, such as impervious surface area limits and secchi disc readings.  Some of those have been challenged, and this decision will no doubt provide ammunition for those who oppose their use.  Nationally, however, this amounts to a very small percentage of the TMDLs that are in place, even if one focuses only on sediment (for which, the court noted, EPA has issued approximately 3700 TMDLs).

In addition, this ruling will have no effect whatever on EPA’s permitting of  industrial and municipal stormwater  discharges, including municipal separate storm sewer systems (“MS4s”), or its ongoing development of stormwater regulations, because these activities are expressly authorized under CWA Section 402(p).  This is especially important, because EPA and many states now recognize stormwater as a major source of contamination and water quality impairment.  For a thoughtful article on this subject and emerging approaches, see Dave Owen, Urbanization, Water Quality, and the Regulated Landscape82 U. of Colo. L. Rev.  431 (April 2011).

Another Temporary Truce in the Arkansas/Oklahoma Water Wars

Posted on April 25, 2013 by Allan Gates

After decades of sparring over nutrient loading in the Illinois River, and following several short term extensions of a previous truce, Arkansas and Oklahoma recently executed an agreement, the “Second Statement of Joint Principles and Actions”, that establishes a procedural framework for attempting to resolve their long running trans-boundary water quality dispute.

The Illinois River heads up in a rapidly developing section of Northwest Arkansas and flows west into a comparatively undeveloped portion of Northeast Oklahoma, where the river is designated by state statute as a scenic river.  For more than two decades Oklahoma has worked to reduce the amount of nutrients, and particularly phosphorus, discharged into the Illinois River watershed.  In 2002 Oklahoma adopted a numeric water quality criterion for Total Phosphorus that many considered impossible to attain in a developed watershed.  In an effort to avoid litigation over the validity of the numeric criterion, Arkansas and Oklahoma entered into an agreement in 2003 known as the Statement of Joint Principles and Actions.  This agreement provided, among other things, that:  (i) Oklahoma would postpone for 10 years the date on which the numeric criterion would be fully effective; (ii) Arkansas sources would take a number of steps to reduce phosphorus discharges; and (iii) Oklahoma would review the existing numeric criterion, with an opportunity for Arkansas representatives to participate, before the end of the ten year period to determine whether the numeric criterion should be changed.

The ten year truce created by the Statement of Joint Principles and Actions was originally scheduled to expire in July 2012.  During the ten year period Arkansas sources made significant progress in reducing the amount of phosphorus they discharged in the watershed.  As a result, phosphorus levels in the Illinois River began to decline and most observers agreed that conditions in the river were significantly improved.  Towards the end of the ten year period Oklahoma undertook a review, with full participation by representatives of Arkansas, EPA, and the Cherokee Nation.  The review ended in a sharply divided report, with Oklahoma representatives stating that no change in the numeric phosphorus criterion was warranted and Arkansas representative stating that significant change was necessary.

As the end of the ten year truce approached, officials from Arkansas and Oklahoma began negotiations once again on how to avoid litigation.  Focus on the potential for costly litigation was sharpened by the fact that EPA had publicly commenced work on a Phosphorus TMDL for the entire Illinois River watershed.  After several agreements on short term extensions of the July 2012 deadline, Arkansas and Oklahoma reached agreement in February 2013 on a Second Statement of Joint Principles and Actions.  This new agreement provides, among other things, that Arkansas and Oklahoma will fund a joint three year water quality study using EPA protocols to determine the threshold Total Phosphorus levels at which shifts in algal species or biomass production occur that result in undesirable aesthetic or water quality conditions.  Oklahoma and Arkansas agree in the Second Statement to be bound by the findings of the joint study, and Oklahoma agrees to adopt a new numeric criterion for Total Phosphorus in the Illinois River if the results of the joint study are significantly different from the existing criterion (i.e., more than -0.010 mg/l or +0.010 mg/l than the existing .037 mg/l criterion).  During the term of the Second Statement of Joint Principles and Actions, both states agree not to initiate or maintain litigation contrary to the terms of the agreement, and the statute of limitations on all claims is extended.  Oklahoma agrees that it will postpone for the duration of the new agreement the date on which its existing, hotly disputed numeric criterion is to be fully effective.

EPA was not a party to the negotiation of the new agreement and it has not announced any formal position on its effect.  It is not clear what impact the new agreement will have on EPA’s work to develop a TMDL for Phosphorus in the Illinois River watershed or on the various NPDES permits for POTWs on the Illinois River that are currently pending review in EPA Region 6.

Can We Please Talk About Outcomes For A Change???

Posted on April 22, 2013 by Rick Glick

I get it that environmental groups place strict compliance with regulatory controls at a premium.  After all, the standards are designed to be protective of the resource, and they are The Law, which must be obeyed. 

But I sometimes find it dismaying when people conflate immediate, measured, and guaranteed compliance with ecological outcomes.  They are not the same.  I have been in settlement discussions in which I propose that we first come to agreement on what’s best for the resource, and then figure out how to make that fit into the regulatory framework, but have had few takers.  The number is the number is the number.

A recent example arises in the context of water quality trading.  EPA policy promotes alternative means of achieving regulatory compliance that promise environmental results at least as good as conventional, engineered approaches, and at lower cost.  For example, if discharge water temperatures are the problem, riparian shade tree planting could substitute for mechanical chillers.  Of course, measureable cooling would be deferred by many years while the trees grow, but the ancillary benefits of watershed restoration to habitat and ecosystem function are intuitive and compelling.  This approach is supported by academia, government, and many in the NGO community.  Some though are skeptical.

The City of Medford, Oregon, is embarking on a riparian vegetation approach to reduce temperatures at its wastewater treatment outfall, in full cooperation with Oregon DEQ.  A regional NGO, Northwest Environmental Advocates, however, has raised objections.  In a letter dated March 15, 2013, NEA asks EPA to examine DEQ’s implementation of the water quality trading policy with reference to Medford.  NEA questions allowance of “credits” for watershed restoration work that upstream nonpoint sources would have to do anyway, and asserts that no credits should be allowed until the new trees actually yield shade.

The problem is that the upstream nonpoint sources are not obligated by law to restore riparian vegetation; they just need to adopt best management practices to avoid further degradation.  More to the point, restoration of the watershed will simply not occur without the funding provided by a point source with a regulatory problem to solve, such as Medford.  By denying the City credits, the incentive to use a watershed approach disappears.  Similarly, if no credits are awarded until the trees are grown, funds that could go toward watershed restoration will be diverted to engineered controls on temperature.  As DEQ Director Dick Pedersen so aptly puts it, “[i]f we ever build a chiller at the expense of ecosystems, we’ve failed.”

Alaska Courts Clarify Application of Antidegradation Procedures

Posted on April 8, 2013 by Eric Fjelstad

Courts in Alaska issued two decisions upholding agency practice in carrying out antidegradation review under the Clean Water Act.  The federal court concluded that adoption of water quality standards does not, itself, require antidegradation review.  In the second case, a state court concluded that guidance may be developed to implement antidegradation regulations and need not be promulgated as a regulation provided it does not contain substantive criteria.

In Native Village of Point Hope v. U.S. Environmental Protection Agency, Alaska native and environmental organizations challenged EPA's approval of the State of Alaska's adoption of a site-specific water quality criterion ("SSC") for total dissolved solids ("TDS").  The SSC was challenged on a number of grounds, including on the basis that neither the State of Alaska nor EPA analyzed the SSC under the relevant antidegradation policy.  The issue before the U.S. District Court for Alaska was whether antidegradation review applied to the adoption of water quality standards ("WQS") or, conversely, only when WQS are translated into permits through effluent limitations.  In a case of first impression in the federal courts, the court ruled for EPA, holding that agencies are not required to undertake antidegradation review for the adoption of WQS; the obligation is only triggered when a WQS is incorporated into a permit through effluent limitations.

In Alaska Center for the Environment v. State of Alaska, environmental organizations challenged the State of Alaska's adoption of antidegradation implementation procedures through guidance, arguing that the procedures should have been promulgated as regulations.  As background, several NPDES permits in Alaska were withdrawn by EPA in the face of arguments from environmental organizations that the State of Alaska lacked antidegradation implementation procedures.  To address this alleged deficiency, the State of Alaska developed a guidance document  which EPA found was consistent with EPA's own antidegradation regulation.  The primary issue in the litigation was whether the State of Alaska was required to promulgate the guidance in the form of a regulation or whether it was permissible rely upon guidance to implement its regulations.  In a decision that turned largely on the State of Alaska's Administration Procedures Act, the court held that it was appropriate for the State to develop the guidance to implement its regulatory program, reasoning that the guidance did not add substantive requirements to existing regulations.

EPA Loses Another Battle in the War Over Guidance: The Eighth Circuit Vacates EPA Policies on Mixing Zones and Bypasses

Posted on March 26, 2013 by Seth Jaffe

On Monday, EPA lost another battle in the war over guidance.  In Iowa League of Cities v. EPA, the 8th Circuit Court of Appeals vacated two letters that EPA had sent to Senator Charles Grassley concerning biological mixing zones and bypass of secondary treatment units at POTWs (also referred to as “blending”, because the POTWs blend wastewater that has not be subject to biological secondary treatment with wastewater that has, prior to discharge).  The Court concluded that both letters constituted promulgation by EPA of effluent limits under the Clean Water Act and that they constituted legislative, rather than interpretive rules (I refuse to refer to “interpretative” rules; sorry).  As a result, the Court vacated the letters due to EPA’s failure to follow notice and comment requirements applicable to promulgation of legislative rules.  Finally, the Court concluded that a duly promulgated rule concerning biological mixing zones might be valid under Chevron, but that a rule barring bypasses of secondary treatment would exceed EPA’s authority under the Clean Water Act.

In first determining whether the letters constituted “promulgation” of an effluent standard, the Court looked to whether the letters were binding on the regulated community.  Relying in part on Appalachian Power Co., the Court concluded that the letters were binding:

If an agency acts as if a document issued at headquarters is controlling in the field, if it treats the document in the same manner as it treats a legislative rule, if it bases enforcement actions on the policies or interpretations formulated in the document, if it leads private parties or State permitting authorities to believe that it will declare permits invalid unless they comply with the terms of the document, then the agency’s document is for all practical purposes “binding.”

As the Court noted with respect to the mixing zone issue, the “letter instructs state permitting authorities to reject certain permit applications, regardless of the state’s water quality standards.”  With respect to the bypass issue, EPA stated that “it will insist State and local authorities comply with” a never-issued policy that precludes the types of bypass at issue.  To try to suggest that words such as “insist” are not binding did not go over well with the Court.  “Just as it did in Appalachian Power, the EPA dissembles by describing the contested policy as subject to change.”

After concluding that the letters constituted promulgation of effluent standards, the Court went on to conclude that the letters constituted legislative, rather than interpretive, rules, and thus were subject to notice and comment rulemaking.  The following is the key paragraph for those of us attempting to beat back the kudzu that is EPA’s reliance on such informal guidance as a substitute for notice and comment rulemaking:

Identifying where a contested rule lies on the sometimes murky spectrum between legislative rules and interpretative rules can be a difficult task, but it is not just an exercise in hair-splitting formalism. As agencies expand on the often broad language of their enabling statutes by issuing layer upon layer of guidance documents and interpretive memoranda, formerly flexible strata may ossify into rule-like rigidity. An agency potentially can avoid judicial review through the tyranny of small decisions. Notice and comment procedures secure the values of government transparency and public participation, compelling us to agree with the suggestion that “[t]he APA’s notice and comment exemptions must be narrowly construed.”

“Layer upon layer of guidance.”  The “tyranny of small decisions.”  I couldn’t have said it better myself.

Kentucky-Specific Water Quality Standard for Selenium

Posted on February 14, 2013 by Carolyn Brown

The Clean Water Act requires states, as well as Indian tribes, to review their water quality standards every three years.  The water quality standards include narrative and numeric criteria that differ based on the type of use designation for the particular stream.  Use designations include warmwater aquatic habitat, cold water aquatic habitat, primary and secondary contact recreation and others.  The Kentucky Division of Water has been engaged in the triennial review of the state’s water quality standards since early 2012.  In the latest development, the agency asked the legislative committee that reviews agency regulations to defer consideration of the rules for another month while the agency takes comment on a change to the state’s standard for selenium.

The Kentucky regulations address a number of changes to the water quality standards and included proposed deletion of the acute water quality criterion for selenium.  The proposal to delete the acute standard was based on findings that the current state standard, which was derived from USEPA guidance, was not based on sound science.  USEPA Region 4 commented on the proposed deletion and identified three options: (1) leave the current acute criterion in place and wait for release of any revisions to USEPA’s selenium criteria, (2) adopt the acute criterion from USEPA’s current national guidance, or (3) adopt an alternate criterion based on other scientifically defensible guidance.

In response, the Division conducted a survey of recent studies of selenium toxicity to aquatic species and determined that it was appropriate to develop state-specific water quality criteria for selenium.  The agency is proposing an acute criterion for warmwater aquatic habitat of 258 ug/L, with an alternate calculation option depending on the sulfate concentration that is present.  The proposed chronic criterion for warmwater aquatic habitat is 8.6 ug/g (dry weight) of whole fish tissue or 19.2 ug/g (dry weight) of fish egg/ovary tissue.  The analysis of fish tissue is triggered when the water column concentration of selenium exceeds 5.0 ug/L.  If the water column result is less than or equal to 5.0 ug/L, the water body is meeting is aquatic life uses.  If the water column result is greater than 5.0 ug/L, then the next step is to determine whether the site is attaining the fish tissue or egg/ovary tissue criterion.

Stay tuned as interested parties weigh in on the state’s proposed action.

Adaptive Management -- Wisconsin’s Innovative Approach to Phosphorus Discharges

Posted on February 12, 2013 by Linda Bochert

In December 2010, the Wisconsin Department of Natural Resources (WDNR) put into place new rules to control phosphorus discharges.  Adaptive management is one of  four compliance options allowed under these new rules.  But what is “adaptive management”?

WDNR developed adaptive management to provide permittees with a less expensive, more flexible compliance option, and describes adaptive management this way:

 “a phosphorus compliance option that allows point and nonpoint sources (e.g., agricultural producers, storm water utilities, developers) to work together to improve water quality in those waters not meeting phosphorus water quality standards.  This option recognizes that the excess phosphorus accumulating in our lakes and rivers comes from a variety of sources, and that reductions in both point and nonpoint sources are frequently needed to achieve water quality goals.  By working in their watershed with landowners, municipalities, and counties to target sources of phosphorus runoff, point sources can minimize their overall investment while helping achieve compliance with water quality-based criteria and improve water quality.”

To be “eligible” to use adaptive management, a permittee must discharge to a water body that is exceeding its in-stream phosphorus criteria on which at least 50% of the total phosphorus loading comes from nonpoint sources, and would have to implement filtration or an equivalent technology to meet the new phosphorus limit.  Unlike water quality trading, which measures compliance with an end-of-pipe effluent limitation, the adaptive management permittee must meet an in-stream concentration of acceptable phosphorus.  Under adaptive management, the phosphorus in the effluent may be reduced over a longer period of time – in some instances, up to several WPDES Permit cycles – as compared to water quality trading which requires the credits to be generated before the permit is issued.  The job of identifying and finding partners falls to the permittee; WDNR does not intend to act as a broker to identify and bring prospective partners together.

An innovative alternative that seeks a watershed approach to control phosphorus, encourages nontraditional partnerships and cooperation between point and nonpoint sources, tries to provide flexibility in timing and doesn’t rely on the traditional and expensive construction of new treatment facilities – how’s it going so far?

For much of industry, forging such partnerships with other regulated and unregulated sources is unfamiliar territory and relying on those other entities to fulfill their commitments when the industrial permittee is the one that must demonstrate compliance is too uncertain to be acceptable.  Many municipalities are more comfortable with partnerships of this sort, but the early experience of one environmentally proactive municipality has demonstrated the enormous amount of time and effort required to take on the role of “champion”, educate and engage other partners in the watershed.  Agricultural interests are initially skeptical – concerned with the potential of taking land out of production.  The environmental advocacy community reaction is mixed.  One ENGO is actively working with the municipality to educate and engage partners and has written a guidance document on how to do adaptive management.  Another ENGO has filed suit against WDNR over WPDES Permits issued with adaptive management compliance schedules in them, reinforcing the reluctance of industrial and municipal permittees to commit to this approach.  And after approving WDNR’s rules in the first instance, EPA now takes such a strict reading of the rules that the intended flexibility may become illusory.

WDNR management is listening to all of this and seeking ways to adjust the implementation of “adaptive management” to respond to these very practical concerns.  No good deed goes unpunished. 

The Georgia Court of Appeals clarifies the antidegradation rule, at least in Georgia

Posted on February 5, 2013 by Patricia Barmeyer

The Clean Water Act’s antidegradation rule has been a fertile ground for dispute and litigation in Georgia, as elsewhere.  A recent decision by the Georgia Court of Appeals, Upper Chattahoochee Riverkeeper, Inc. v. Forsyth County, 734 S.E 2d 242 (Ga. App. 2012), has interpreted the Georgia version of the Rule and provided some clarity for POTWs and others seeking NPDES effluent limits. 

Georgia’s Antideg Rule is identical to the federal rule and provides that in the case of a proposed discharge to high quality waters, that quality shall be maintained unless allowing lower water quality is “necessary to accommodate important economic or social development,” and water quality to protect existing uses is assured.

The Rule is not a model of clarity, to say the least, and has been subject to varying interpretations.  EPA has chosen not to provide more specific direction and has, on multiple occasions, reiterated that it is up to the States to decide how to interpret and apply the Antideg Rule, through each State’s implementation procedures.  

Georgia EPD’s implementation procedures interpret the rule to require a determination whether the proposed new or expanded discharge is “necessary to accommodate important economic or social development….”  If it is determined the discharge is “necessary,” that is, that a no-discharge alternative is not economically feasible, then EPD proceeds to consider the application and to impose permit conditions based on the applicable technology-based standards and in-stream water quality standards. 

In contrast, the environmental groups, and an Administrative Law Judge, have taken the position that the Antideg Rule requires EPD to consider whether “allowing the lower water quality resulting from the permitted discharge is actually necessary.”  That reading led the ALJ to conclude that, without regard to cost or benefit, the permit limits for the POTW must be set at the lowest level that is technologically feasible, so long as the permittee can afford it.  As interpreted by the ALJ, the antidegradation analysis would be not just the beginning of the analysis of a proposed new discharge, but also the end point.  According to that view, the antideg analysis would ask, not just whether the discharge is justified, but also, what is the lowest limit that is feasible.  Application of the Antideg Rule in this fashion would short-circuit all considerations of in-stream water quality standards and technology-based limits.  It would eliminate any distinction between POTWs and industrial facilities -- they both would have to meet the lowest limit that is technologically feasible that they can afford.

The Georgia Court of Appeals has now agreed with EPD’s reading of the Antideg Rule.  The  court held the rule requires only a determination whether lower water quality generally is necessary to accommodate economic or social development, not a permit-specific analysis of whether the exact effluent limits in the permit are necessary.  The opponents to the permit have asked the Georgia Supreme Court to take up the issue; a decision on the petition for certiorari is expected by mid-2013.

SUPREMES CONFIRM NO DISCHARGE PERMIT NEEDED FOR POLLUTED WATER TRANSFERS WITHIN SAME RIVER

Posted on January 10, 2013 by Richard Glick

On January 8, 2013, the U. S. Supreme Court unanimously held that flow from an improved portion of a waterway into an unimproved portion of the same waterway—even if polluted—does not qualify as “discharge of pollutants” under the Clean Water Act (CWA).  Although this case arises in the context of a municipal separate storm sewer system (MS4), it has major implications for dam owners everywhere.  The case reaffirms evolving doctrine that dams are not point sources requiring National Pollutant Discharge Elimination (NPDES) permits per Section 402 of the CWA.

In Los Angeles County Flood Control District v. Natural Resources Defense Council, environmental groups brought a CWA citizen suit against the District for violating the terms of the District’s NPDES permit to operate the MS4 facilities.  It was undisputed that water quality standards had repeatedly been exceeded for a range of pollutants, as measured at the District’s monitoring stations in the Los Angeles and San Gabriel Rivers.  The District collected storm water in concrete channels before discharging back to the river, and the monitoring stations were within the concrete channels.  It was also undisputed that many other upstream parties contributed to the contamination.  

Plaintiffs argued that since the monitoring stations were within the control of the District, the District had responsibility for meeting standards.  But that was not the issue for the Court.  Instead, the Court focused on whether a “discharge of pollutants” occurs when polluted water flows from one portion of a river, through an engineered improvement, and then back again to the same river.  The Court answered in the negative, citing its 2004 decision in South Fla. Water Management Dist., v Miccosukee Tribe.  In Miccosukee, the Court held that pumping polluted water from one part of a water body to another part of the same water body is not a discharge of pollutants.

This decision should come as welcome news to dam and hydroelectric plant owners.  Prior to Miccosukee and now LA County, the federal Courts of Appeal simply deferred to EPA judgment as to whether a dam could be said to “add” pollutants originating upstream when it passes them through penstocks or spillways to the river below.  The Supreme Court, however, has firmly established a rule of law that CWA Section 402 is implicated only where the upstream and downstream river segments are “meaningfully distinct water bodies,” a condition that will rarely exist for in-river dams.

GREAT LAKES ECOSYSTEM INDICATORS

Posted on January 4, 2013 by David Ullrich

Tremendous progress has been made in protecting and restoring the environment over the past 40 years since the passage of major legislation at the federal, state, and provincial levels in the United States and Canada.  However, our skill at measuring that progress is somewhat limited, and we may not have the kind of information we need to judge the health of our ecosystems or the effectiveness of our programs.  There have been some good efforts on an international, national, state, and provincial basis to evaluate the state of the environment using certain indicators, but one area needing much more attention is the Great Lakes. 

Although there are many indicators monitored on a continuing basis in the Great Lakes, the real difficulty has been synthesizing the information in a way that puts officials in a position to communicate effectively with the public, policy makers, and managers about whether the Great Lakes are getting better, worse, or staying the same.  The International Joint Commission (IJC) initiated an effort recently through its Water Quality Board (WQB) and Science Advisory Board (SAB) to identify a limited number of core indicators for this freshwater resource.  What’s needed now is a consensus among the scientific and policy leaders on the Great Lakes on the “few indicators that tell us the most” about the waters.

It was not hard to tell the Great Lakes were in trouble when enough dead alewives washed up on its shores requiring front end loaders to remove them, the Cuyahoga River and other tributaries caught fire, and Lake Eric was declared “dead” because of massive algal blooms.  Many of these conditions on the Great Lakes led to both a public outcry and Congressional action in order to deal with the lakes’ water pollution and other environmental problems.  As programs were put in place to keep oil out of the rivers and reduce nutrient loadings to the lakes, significant visible improvements were seen.  The underlying data was available to support the observations, but the visible improvements plus much better fishing success told the story in an easily observable way. 

Things are much more complicated now.  When looking at the fundamental three legged stool  supporting the Great Lakes’ ecosystem, being the chemical, physical, biological integrity of the resource, it is not easy to gage.  With regard to chemicals, very low concentrations of legacy pollutants like PCBs and dioxins can cause serious problems.  Likewise, ongoing contamination from airborne deposition of mercury is a real concern.  New chemicals such as flame retardants are the next problem area with which to deal.  Invasive species such as the zebra and quagga mussels, the ever present sea lampreys, and the threat from the Asian carp are a constant problem for maintaining the biological balance in the system.  From a physical standpoint, expanding urbanization, suburban sprawl, and the manifestations of climate change are also adding tremendous pressure on the Great Lakes.  What’s needed is a core set of chemical, physical, and biological indicators of the health of the ecosystem and the effectiveness of the programs to protect and restore it.

Good progress is being made on this front.  After several months of work by some of the top Great Lakes’ scientists and policy makers, a group of just over twenty indicators has been preliminarily identified, with a smaller group as the core.   They include:
    Physical: Coastal wetlands, land cover, and tributary physical integrity
    Chemical: Nutrient concentrations and loadings, and persistent bio - accumulative toxics
    Biological: Lower food web productivity/health, fish species of interest, harmful and nuisance algae, aquatic invasive species

Much of the foundation for the work done recently comes from what is known as the State of the Lakes Ecosystem Conference (SOLEC), which is a large gathering, primarily of scientists, held every two years to review and evaluate a large number of Great Lakes’ indicators on the Great Lakes.

What needs to happen next is for the IJC first to adopt a set of core indicators as the ones that tell us the most about the resource, then inform the U.S. and Canadian governments of its findings.  Under the recently updated Great Lakes Water Quality Agreement, the parties are responsible for establishing ecosystem indicators for the Great Lakes.

With a set of core indicators, both countries will be in a much better position to communicate with the public, elected officials, and managers about the health of the ecosystem and the effectiveness of programs.  In addition, our governments will be in a position to make better choices about the allocation of increasingly scarce resources to maximize the return on investment for improving the health of the Great Lakes, the largest, surface freshwater system in the world.

New Hampshire's Great Bay, Nitrogen, and the Limits of Technology

Posted on December 26, 2012 by Gregory H. Smith

As the Clean Water Act celebrates its 40th anniversary, it has ignited a controversy in New Hampshire with potentially hundreds of millions of dollars at stake.  In the law’s early days,  publicly owned treatment works (“POTWs”), mandated and financed in large part with federal funds, were viewed as the “good guys” in the national effort to restore quality in receiving water bodies into which raw sewage was being discharged.  That view of POTWs seems to have changed in New Hampshire, at least as relates to the State’s largest saltwater estuary; the Great Bay.  Faced with the potential need to finance significant POTW upgrades or reconstruction, New Hampshire POTWs are challenging EPA’s permitting decisions in the courts, through administrative channels and in the press.

As we know, POTWs are regulated through National Pollutant Discharge Elimination System (“NPDES”) permits that monitor and control a variety of effluent criteria.  Interestingly, however, New Hampshire was and remains one of the few states that has not obtained authority to issue new and renewed NPDES permits.  Because of this status as a non-delegated state, dischargers in New Hampshire with expiring permits must apply to the federal government for renewal.  As environmental regulation has progressed, however, and as federal funds have diminished or disappeared, POTWs and the towns and sewer districts that operate them have found themselves opposed to the EPA’s efforts to impose stricter standards  to address pollutants that were not of primary concern when the POTWs were constructed and initially permitted.

In New Hampshire, this is seen vividly in NPDES renewal efforts EPA is undertaking for several POTWs that discharge under expired and expiring permits, directly or indirectly, into the Great Bay estuary located on the State’s coast.  Once a rich habitat for oysters, eel grass and other sea life, Great Bay is now stressed by a variety of factors including both point and non-point discharges as well as other environmental factors.   At the heart of the controversy  in New Hampshire is EPA’s intention to reduce effluent limitations for nitrogen to as low as three parts per million (the limits of technology) in order to ameliorate nitrogen related problems in Great Bay.  From the municipalities and POTWs perspective, the costs to comply with these new lower limits are exorbitant.  One widely cited study estimates that, for the Great Bay estuary POTWs to comply with the new nitrogen limit, it will cost in excess of one half billion dollars in capital,operation and maintenance expenses.  Those costs will, of course, be passed along to a relatively small population of ratepayers. 

A coalition of communities with affected POTWs has joined forces in response, proposing “adaptive management programs” combining somewhat lower discharge limits with comprehensive non-point controls aimed together at achieving EPA’s stated goals.  It is unclear at this time whether those efforts will be successful.  The coalition communities certainly have in mind the experiences in Chesapeake Bay, or closer to home in neighboring and similarly non-delegated Massachusetts, where EPA is using its  Residual Designation Authority (“RDA”) to require permits in the Charles River watershed.  EPA has been public with its view that the Charles River RDA program may become a model for watersheds elsewhere in New England and nationwide.  It is thought that an adaptive management program as proposed by New Hampshire’s coalition communities would obviate the need to utilize RDA for Great Bay, but that issue remains to be addressed in the future.

Numeric Nutrient Criteria - High Stakes in the States

Posted on December 4, 2012 by John Milner

On March 13, 2012, eleven environmental organizations, led by Gulf Restoration Network ("GRN"), filed
a federal Clean Water Act (CWA) citizen suit which demanded that the U.S. Environmental Protection
Agency (EPA) set federal numeric standards for nitrogen and phosphorus for water bodies within the 31
states comprising the Mississippi River Basin ("Basin States"). Gulf Restoration Network v. Jackson,
E.D. La., No. 2: 12-cv-00677 ("GRN Suit"). The complaint alleges that EPA has failed to develop
numeric water quality criteria for nitrogen and phosphorus in the Basin States. EPA's answer states that it
is appropriately deferring to each state to promulgate numeric nutrient criteria ("NNCs") that satisfy
Clean Water Act water quality standards within the state and that, consequently, federal NNCs are not
appropriate. The trial judge ruled on September 19, 2012 that the case will be decided on "cross-motions
for summary judgment, with no initial disclosures or other discovery." In the same order, the judge set a
briefing schedule for the parties (including numerous entities to which the court granted permission to
intervene) that will extend through the beginning of June of next year.

The GRN Suit, as well as other similar suits that are active in other regions, have prompted many state
environmental agencies to work diligently, pursuant to EPA's deference and also its demand, to develop
NNCs as quickly as possible. If EPA wins the GRN Suit, the Basin States will have to be ready to go
forward with promulgation of their NNCs. If EPA loses, they may be subjected to more stringent federal
NNCs on a "one size fits all" basis. A settlement could mean an even different outcome for all ofthe
parties.

In Mississippi, the state's Department of Environmental Quality ("MDEQ") has formed a Nutrient
Technical Advisory Group (TAG) to develop scientifically defensible NNCs that are appropriate for
Mississippi's surface waters. The TAG is composed ofMDEQ staff, MDEQ's external consultants and
in-state university personnel who have water quality expeiiise and is meeting on a regular basis. MDEQ
staff members have stated that the agency's plan is to have draft NNCs developed for all state waters,
excluding the heavily agricultural Delta counties, by June 30, 2013. The draft NNCs for the Delta are to
be developed by November 30, 2014. MDEQ wil then publish these draft NNCs for public comment.

MDEQ has held several stakeholder meetings to discuss the development of Mississippi's NNCs and to
provide an opportunity for questions and comments. The MDEQ staff members have consistently
explained that they are considering "what is protective of the environment" rather than "what is
technically achievable." The new NNCs wil be "worked into permits" as they come up for renewal and
permittees wil be allowed a "reasonable time frame" to come into compliance with the new NNCs.

The key issue for the regulated community in Mississippi, as in other states, will be the cost of
compliance with these new NNCs, which could bear a very expensive price tag. In Florida, for example,
a national environmental engineering consultant prepared an economic analysis of proposed NNCs. The
estimate for direct compliance costs ranged from $ 1.5 bilion annually (best management practices for
impaired water categories) to $4.5 billion annually ("end of pipe" requirements for all water categories).
Regulated communities in Mississippi and in other states across the country are engaging with scientific
and economic data and consultants in order to have an impact concerning this volatile issue. A lot is on
the line.

Consumer’s Guide to the Great Lakes Water Quality Protocol of 2012

Posted on November 28, 2012 by Ronald R. Janke

My views of the Great Lakes Water Quality Protocol of 2012, which was signed on September 7, 2012, by the United States and Canada, are influenced literally by where I sit.  For almost four decades I have daily seen the broad expanse of Lake Erie from my office window.  For as many days as I can in the summer, I sit on its beaches and swim in its waters.  Occasionally, I have sat on boats and fished Lake Erie.  My view of the Protocol is also influenced by the existence of many other Great Lakes programs, such as the Great Lakes Initiative, the Lakewide Management Plans, Remedial Action Plans, the Great Water Program, the Binational Toxics Strategy, Great Lakes 2001 as well as several State of Ohio programs aimed specifically at addressing Lake Erie’s environmental issues.

From where I sit, my view of the Protocol is not whether it is a comprehensive program or whether it recognizes the values of the Great Lakes.  Rather, my view is whether it will assist in addressing the most critical threats now facing the Great Lakes, and to Lake Erie in particular.   Those threats are, in my opinion, irreparable damage to the Lake Erie fishery and the continued inability to enjoy its beaches and other locations for swimming on many summer days due to the combined impacts of CSOs and excessive algae blooms due to nutrient loadings.

An invasion of the Asian carp into the Great Lakes threatens a permanent change in its fishery, the nature of which cannot be predicted.  The Asian carp would determine what the Great Lakes fishery would be.  Combined sewage overflows into the Great Lakes continue to produce beach closings for days after rainstorms forty years after the enactment of the Federal Water Pollution Control Act, and beach closings can be expected for at least another 40 years based on the current trajectory of CSO Control Projects.  The current generation of algae blooms in Lake Erie has produced swimming advisories for large portions of the Lake that persist for weeks.

Of the many issues that the Protocol addresses, preserving and enhancing the public’s ability to swim and fish in the Great Lakes are the most important.  For the public to fully value and to love the Great Lakes, they need to be able to touch it by wading, swimming or fishing.  Public support for the many programs under the Protocol will depend ultimately on the public’s love for the Great Lakes.

COURTS FRIENDLIER TO EPA IN CLEAN WATER ACT CONTEXT THAN CLEAN AIR ACT?

Posted on September 19, 2012 by Rick Glick

In his blog post of August 27, Rob Brubaker reported on three cases in which the courts refused to grant deference to EPA decisions under the agency’s Clean Air Act authority.  EPA has fared a bit better in two recent Clean Water Act cases.

In Upper Blackstone Water Pollution Abatement District v. EPA case, the issue was whether EPA properly issued a stringent NPDES permit renewal to a sanitary district to control excessive nitrogen and phosphorus loading.  The First Circuit Court of Appeals rejected the district’s argument that EPA should have waited until the district could complete its modeling effort, even though the model did not seem close to ready, and that EPA did not apply the best science.  The court declined to conduct a de novo review of EPA’s scientific analysis, limiting its inquiry to whether EPA followed the appropriate administrative process, based its decision on record evidence and clearly articulated its reasoning. So long as the criteria imposed are within the “zone of reasonableness”, the court will not strike it down.

Interestingly, the Upper Blackstone court also rejected the district’s argument that the new permit is improper because even with stricter criteria, it would not be sufficient to correct the eutrophication problem in the watershed.  The court set that aside, noting that the CWA contemplates multiple sources of contamination and no one party is responsible for cleaning up the river. 

The Upper Blackstone case is consistent with the U. S. District Court’s decision in the Northwest Environmental Advocates v. EPA, which I discussed in my March 23 post.  In the latter case, the court upheld EPA’s approval of Oregon’s numeric temperature standards, deferring to the EPA’s scientific expertise.  It took issue with the narrative Natural Conditions Criteria because it was so broad that the court concluded it supplanted numeric standards.  The court left the door open for the Oregon Department of Environmental Quality to rewrite the narrative standard for EPA review, based on the agencies’ own review of the science and a good explanation in support of the standard. 

It appears the theme running through three Clean Air Act cases cited in the Brubaker post is that the reviewing court found no authority supporting EPA’s action, or that EPA’s interpretation defied the plain meaning of the statute.  In the Clean Water Act cases, EPA overreaching on the Upper Blackstone permit or approval of Oregon water quality standards was not at issue.  The focus instead was on whether EPA demonstrated it properly considered the best science available under the authority it had, and then explained how it got to its decision.  In that context, EPA and state regulatory agencies will win more than they lose.

What Ever Happened to Reasonable Further Progress?

Posted on August 8, 2012 by Robert Falk

Under the federal Clean Water Act (CWA), most municipalities in the United States are now required to have National Pollutant Discharge Elimination System (NPDES) permits for discharges of stormwater/urban runoff.  As intended by Congress, both the U.S. Environmental Protection Agency (EPA) and authorized state NPDES permit writers originally took a programmatic approach relative to the requirements they put into such Municipal Separate Storm Sewer Systems or “MS4” permits.  Over time, though, municipalities have, in various ways, been required to address water quality standards more directly, including where such standards are expressed quantitatively. 

In California, this has manifested itself in the issuance of MS4 permits containing provisions called “Receiving Waters Limitations,” which, among other things, preclude the permitted municipal stormwater discharges from “causing or contributing to a violation of an applicable water quality standard.”  Since this ambitious goal is a tall order that likely cannot be met without the construction of large, capital-intensive detention and treatment facilities for which no funding is available, other language contained in these MS4 permits has instructed the municipality that if “exceedances of water quality standards persist,” they must evaluate and submit plans to improve their stormwater management programs to address the situation and then implement such plans and improvements according to a schedule they propose – an “iterative process” that envisions reasonable further progress towards the achievement of water quality standards over time and which inherently recognizes that resource and feasibility constraints may inform the pace of that progress.

Last year, in NRDC v. County of Los Angeles, et al., 636 F. 3d 1235 (9th Cir. 2011), the U.S. Court of Appeals ruled that demonstrating compliance with the iterative process language in these MS4 permits did not create a safe harbor and shield a municipality from direct enforcement of the Receiving Water Limitations themselves, including by means of a citizens’ suits.  The U.S. Supreme Court recently granted cert. in this case, raising a glimmer of hope for municipalities that a reasonable further progress approach might somehow be restored.

Unfortunately, the High Court may well not speak directly to this issue notwithstanding its practical import for municipalities.  Its cert. grant instead requested briefing and argument on the more unusual and academic issue of whether water that flows from one portion of a river that is navigable water, through an MS4 or other engineered channel, and into a lower portion of the same river is “discharge” from an “outfall” requiring an NPDES permit.  As its cert. grant itself suggests, this is an issue the U.S. Supreme Court likely already addressed in South Florida Water Management District v. Miccosukee Tribe of Indians, 541 U.S. 95 (2004).  Accordingly, if the Ninth Circuit’s decision is reversed on this basis and without a discussion of the broader issues that caused it to arise, it will be left to Congress, EPA, or state permit writers to decide if they are willing to restore a reasonable further progress approach to municipal stormwater permitting.

Water Quality Trends in the Northwest (Fish Consumption Rates)

Posted on July 9, 2012 by Kevin Beaton

The criterion to protect human health found in state water quality standards under the Clean Water Act are getting more stringent in the Northwest.  This is occurring because people in the Northwest supposedly eat more fish from Northwest waters than other parts of the country.  The esoteric standard setting process to protect people from toxic pollutants in surface waters is premised upon numerous risk based assumptions which include the amount of surface water an average person consumes combined with the amount of fish consumed from such waters.  The more water and fish people consume the more stringent the criteria becomes.  EPA establishes national defaults for states to use in their human health standard setting process for both water ingestion and fish consumption rates (“FCR”).  The national recommended FCR is 17.5 g/day.  A detailed description of the standard setting process can be found in EPA’s Methodology for Deriving Ambient Water Quality Criteria for the Protection of Human Health (2000).

Until recently, use of the EPA default FCR was acceptable in the Northwest.  However the state of Oregon recently adopted (and EPA approved in 2011) a FCR ten times higher than the national default.  The principal driver behind Oregon’s change was a FCR study funded by EPA in the 1990’s that evaluated the FCR of members of a number of Northwest Tribes in Oregon, Washington and Idaho.  See A Fish Consumption Survey of the Umatilla, Nez Perce, Yakima, and Warm Springs Tribes of the Columbia River Basin (CRITFC 1994). The CRITFC study showed that Tribal members consumed much higher rates of fish.

In May 2012, EPA disapproved Idaho’s human health criteria in Idaho’s water quality standards which were based on EPA’s national recommended default FCR.  EPA disapproved Idaho’s standard because the state did not “consider” the CRITFC study.  (Idaho believes it did consider the CRITFC study.)  EPA also questioned whether Idaho’s standards were protective of Oregon’s downstream standards.  Idaho now has 90 days to respond to EPA’s disapproval.  Meanwhile the state of Washington is in the process of reevaluating its human health standards and FCRs. Whether this trend moves into other states or other EPA regions remains to be seen.

One might legitimately ask whether this issue is nothing more than an academic exercise amongst toxicologists and risk assessors.  Ultimately the answer to that question is found in the Clean Water Act itself.  Roughly calculated, increasing the FCR ten times equates into the criteria for many toxic pollutants becoming ten times more stringent.  Under the Clean Water Act NPDES Permit limits must be established to meet these new criteria.  Under the new standards adopted by Oregon some of the toxic pollutants that are likely to present particularly challenging compliance issues for permittees will include mercury, PCBs and arsenic, as the presence of these pollutants are somewhat pervasive in Northwest waters.  In most instances, requiring permittees to implement costly pollution controls to attempt to achieve the new criteria at the end of the pipe will have minimal affect on achieving the new stringent standards in the receiving waters.  In light of EPA’s recent disapproval of Idaho’s standards, the state must now decide if it needs to amend its criteria or conduct its own fish survey statewide.  Untested legal issues are raised by EPA’s disapproval like whether a state must establish a state-wide FCR based on a very small percentage of the population or because a downstream state (Oregon) has decided to adopt more stringent criteria.  Like many increasingly complex issues under the Clean Water Act, these issues may have to be settled in federal court.

OREGON TEMPERATURE WATER QUALITY STANDARDS UPHELD (SORT OF)

Posted on March 23, 2012 by Rick Glick

In a 50 page opinion issued February 28, Federal Magistrate Judge Acosta handed EPA and the Oregon Department of Environmental Quality (DEQ) a partial victory in Northwest Environmental Advocates v. EPA et al.  The decision upheld EPA’s approval under the federal Clean Water Act of the Oregon DEQ’s numeric temperature water quality standards, while rejecting certain narrative standards.  NWEA also challenged the biological opinions issued by the National Marine Fisheries Service and U. S. Fish and Wildlife Service under the Endangered Species Act.  The Services concluded that the Oregon temperature and intergravel dissolved oxygen standards would not jeopardize listed salmonid species, and those agencies did not fare as well in the case.

Oregon’s temperature standards were adopted in 1996 and promptly attacked.  In 2003 EPA Region 10 adopted its own Temperature Guidance, and Oregon’s temperature standards were reformulated.  NWEA again found the revised standards wanting and brought the case at issue.  The judge upheld DEQ’s numeric temperature standards, despite evidence that the standards were less than optimal for fish, deferring to the scientific expertise of the government. 

The judge found fault, however, with narrative standards that deal with “nonpoint sources” of heat.  A point source is a discrete, end-of-pipe discharge to a waterway, whereas nonpoint sources are diffuse, such as runoff from a field.  The Clean Water Act regulates point sources through a permit program, while nonpoint source control is mostly aspirational, although it does direct states to develop best management practices and measures for controlling nonpoint source pollution.  Under the Oregon narrative standards, a nonpoint source that adopts “best management practices” is deemed to be in compliance. 

The court found that this formulation undermines DEQ’s numeric standards as it provides a substitute for actual compliance.  The same reasoning was applied to the so-called Natural Conditions Criteria, which provide that compliance is excused if natural conditions exceed standards.  The court found that such an exemption supplants otherwise lawful standards.
 
The court’s objections to the narrative standards notwithstanding, neither the Clean Water Act nor state law authorize direct regulation of nonpoint sources.  The narrative standards were Oregon’s attempt to address pollution from nonpoint sources without adopting a new regulatory program.  It seems the court reacted to the blanket exemptions provided in the rules, and it further seems that Oregon can revise them and pass muster.  The deference shown the agencies on the science suggests that the court will allow some leeway on language used to deal with nonpoint sources and the effects of natural conditions.

No such deference was granted to the federal fisheries services.  On remand they will have to prepare a new biological opinion that accounts for Evolutionary Significant Units (i.e. sub-groups of salmonids), potential for recovery, baseline conditions and cumulative effects.  Further, the Fish and Wildlife Service was chastised for considering factors other than the best scientific data available in formulating its opinion.  That is, FWS seemingly bowed to pressure to support the EPA Temperature Guidance, even though it believed that temperatures for bull trout provided for in the Guidance were not what FWS considered to be optimal. 

The net result of the many years of litigation over Oregon’s temperature standards is that Oregon’s approach, and EPA’s approval under the Clean Water Act, were largely validated.  Problems with narrative standards should be correctable.  Whether on reanalysis the Services find that the standards are protective of listed species, as required under the Endangered Species Act, remains to be seen.

The Fate of Georgia EPD’s Antidegradation Policy is Muddier than Ever

Posted on February 23, 2012 by Richard Horder

Current federal law requires states to develop and adopt a statewide antidegradation policy to protect existing in-stream uses for high quality waters.  Georgia has done so under Rule 391-3-6-.03.  Georgia’s antidegradation policy describes what requirements must be met before the State issues a permit under the National Pollutant Discharge Elimination System (“NPDES”) and allows a wastewater point source (i.e. wastewater treatment plan) to discharge pollutants into surface waters.  However, in apparent response to the U.S. Environmental Protection Agency’s (“EPA”) potential revision of its requirements for state antidegradation policies and an Administrative Law Judge’s recent ruling, the Georgia Environmental Protection Division (“EPD”) published proposed amendments to its antidegradation policy in September 2011.

In its proposed amendments, EPD attempts to set out exactly when the antidegradation review process is triggered and what an applicant requesting a new or expanded point source discharge must demonstrate to obtain the permit.  EPD’s proposed rule and related guidelines explain the three basic steps as follows: (1) applicant may demonstrate that proposed discharge will not result in “significant lowering of water quality” (if satisfied, no antidegradation analysis is required); (2) if water quality is significantly lowered, applicant must demonstrate that discharge will accommodate important social or economic development; and (3) applicant must demonstrate that no reasonable alternatives exist that would provide the needed wastewater capacity without authorizing a new or expanded wastewater discharge into surface waters.  The key to this new procedure is the definition of “does not significantly lower water quality.”   Specifically, if the proposed discharge of a pollutant is 10% or less than the remaining assimilative capacity for that pollutant in the receiving stream, then the new discharge per se “does not significantly lower water quality” and no antidegradation analysis is required.  These amendments appear to respond to EPA’s concerns over EPD’s implementation of an antidegradation policy, and clearly appear to respond to the ALJ’s decision in Upper Chattahoochee Riverkeeper, Inc. v. Forsyth County, Georgia

In September 2010, Upper Chattahoochee Riverkeeper, Inc. (“UCR”) filed a petition challenging the issuance by EPD of an NPDES permit (“Permit”) authorizing Forsyth County to discharge 6 million gallons per day (“MGD”) of wastewater into the Chattachoochee River from the County’s existing waste water treatment facility and the new Shakerag facility.  The Permit set limits of 200 colony-forming units per 100 milliliters (“cfu/100mL”) and 0.3 milligrams per liter (“mg/L”) for fecal coliform bacteria and phosphorous, respectively.  UCR claimed that the Permit, specifically the expanded limits, threatened the present and future health of the Chattahoochee River without EPD having undertaken a proper study, modeling or antidegradation analysis to show that the degradation of the river was necessary to accommodate Forsyth County’s economic and social development. 

In a decision found later to be overreaching, the ALJ held that any lowering of water quality in the receiving water triggers an antidegradation review and such review must analyze both the technical and economic feasibility of any alternatives, as well as a no-discharge permit alternative.  The ALJ made this conclusion in part by referencing EPD’s failure to define certain terms and therefore the ALJ adopted the EPA’s guidelines.  More surprising, the ALJ also adopted the permit discharge limits suggested by UCR which were much lower than those in the original permit or even those allowed for recreational waters by Georgia’s Department of Natural Resources.  The ALJ then remanded the permit to the Director of EPD for reissuance with revised monthly discharge limits of 23 cfu/100mL for fecal coliform bacteria and 0.08 mg/L for total phosphorous.   

Forsyth County appealed to the Superior Court of Forsyth County which reversed the ALJ’s decision finding that the ALJ had exceeded her authority.  The Court concluded the ALJ could not create an enhanced review by wholesale adoption of EPA guidelines nor set specific effluent limits.  EPD’s recent proposed amendments state clearly that effluent limits cannot be set pursuant to an antidegradation analysis, but only by EPD pursuant to Rule 391-2-6-.06.  The Court remanded the matter to the ALJ, ordering the antidegradation review standard be applied as codified in EPD’s implementing procedures without reference to EPA guidance documents. 

However, the battle is not over as UCR has appealed this decision to the Georgia Court of Appeals. As of this writing, both parties have submitted their briefs for review and oral argument is yet to be set.  In light of EPD’s recent proposed amendments, this decision is one to watch as the appellate court’s holding could have a significant impact on restrictions in future NPDES permits.

IS IT SOMETHING IN THE AIR OR INSTEAD IN THE WATER? THE ROSE ACRE CASE

Posted on February 7, 2012 by Susan M. Franzetti

A rather surprising turn of events occurred recently in North Carolina, but the underlying reasons still remain unclear.  On January 11, 2012, the North Carolina Environmental Management Commission (“EMC”), by a 4-3 vote, vacated an Administrative Law Judge’s (“ALJ”) decision on summary judgment that the Rose Acre egg farm’s airborne ammonia emissions are not subject to regulation under, and do not require, a National Pollutant Discharge Elimination System (“NPDES”) permit.  The ALJ’s Decision and the parties’ pleadings are available here.The EMC remanded the matter back to the ALJ, August B. Elkins II, for a full evidentiary hearing.  Thus, the case raises anew the question of whether a discharge to air can constitute a point source discharge to navigable waters of the United States which requires a NPDES permit under the Clean Water Act,.  The answer may depend on whether such a discharge is found to remain “in the air” and not make its way by land “into the water.” 

On October 17, 2011, ALJ Elkin found that the Rose Acre facility does not discharge or have the potential to discharge process wastewater (or manure, litter) to navigable waters of the United States.  Judge Elkin’s relied on the March 2011 decision by the Firth Circuit Court of Appeals in National Pork Producers Council v. EPA, in which it held that the U.S. Environmental Protection Agency lacked the authority to require a NPDES permit for a facility that “proposes to discharge” or any facility that has not yet discharged into a navigable water of the United States.  Judge Elkin held that the DENR has no authority to require Rose Acre to obtain an NPDES Permit. 

Rose Acre is the site of 14 high-rise hen houses with a total of four million egg laying hens, located within the Tar-Pamlico River Basin in North Carolina.  Rose Acre operates what is called a “dry-litter facility” that does not directly discharge into any waters.  In 2009, before the Fifth Circuit’s decision in National Pork Producers Council that only CAFOs that actually discharge were required to secure a NPDES permit, Rose Acre applied for a NPDES permit.  The Division of Water Quality of the North Carolina Department of Environment and Natural Resources (“DENR”) issued a NPDES permit to Rose Acre, which included conditions requiring amendment of the facility’s Best Management Plan (“BMP”).  Rose Acre appealed, contending that it no longer needed an NPDES permit as well as challenging a number of the BMP conditions on the grounds that they exceeded the DENR’s regulatory authority.  The ALJ granted Rose Acre summary judgment.

Existing precedent supports the ALJ’s decision.  Both the Second and Tenth Circuit Court of Appeals have ruled that air emissions, even where there is atmospheric deposition into navigable waters, are not regulated by the Clean Water Act.  The Second Circuit so held in its 2000 decision in No Spray Coalition, Inc. v. City of New York, dealing with insecticide spray to eradicate mosquitoes.  In No Spray Coalition, the Second Circuit found that:
       While the trucks and helicopters used to spray insecticides may be point sources…they discharge the    insecticides into the atmosphere and not into navigable waters.  It would be stretching the language of the [Clean Water Act] well beyond the intent of Congress to hold that the de minimus incidental drift over navigable waters of a pesticide is a discharge from a point source into those waters. The fact that a pollutant might ultimately end up in navigable  waters as it courses through the environment does not make its use a violation of the Clean Water Act…To so hold would bring within the purview of the Clean Water Act every emission of smoke, exhaust fumes, or pesticides in New York City.

In 1997, the Tenth Circuit, in Chemical Weapons Working Group v. U.S. Department of the Army, refused to apply the Clean Water Act § 301(f) prohibition against disposal of chemical weapons into waters to smokestack emissions from a chemical weapons incinerator.  The Tenth Circuit emphasized the potential duplication of regulation by the Clean Air Act as well as finding that under § 301(f), Congress clearly intended to authorize the incineration of chemical weapons.  The Tenth Circuit also viewed the attempt to regulate stack emission under the Clean Water Act as contrary to plain old common sense.  (“Although Plaintiffs may be correct in arguing that an object may fly through the air and still be ‘discharged…into the navigable waters’ under the Clean Water Act, common sense dictates that [the] stack emission constitute discharges into the air – not water- are therefore beyond § 301(f) reach.”). 

Similarly, in American Canoe Assn. v. D.C. Water and Sewer Authority, the U.S. District Court for the District of Columbia rejected allegations that the D.C. Sewer Authority violated its NPDES permit by failing to install odor controlling carbon filters on sewer vents.  The court found that attempts to control sewer gas or hydrogen sulfide fumes emanating from sewers in a NPDES permit are “unrelated to the general purposes of the CWA” and unenforceable obligations. 

During oral argument on its challenge to the ALJ Elkin’s Rose Acre decision before a panel of the EMC, the DENR’s counsel appears to have successfully changed the focus of the legal inquiry from what’s in the air to what’s in the water?  In its Exceptions to the ALJ’s Entry of Summary Judgment, the DENR contended that it had not attempted to regulate airborne emissions of ammonia.  Instead, it now contends that Rose Acre does discharge to navigable waters, citing the fact that “with a rain event the feathers and dust from the ventilations fans at [Rose Acre] are flushed into a stormwater pond and then into waters of the State.  The DENR further relied upon the comparative results of surface water monitoring taken before and the Rose Acre hens were stocked, which showed higher levels of ammonia nitrogen, total inorganic nitrogen, phosphorus and fecal coliform in surface water.  Thus, the DENR took the position that although pollutants may initially be discharged “into the air,” if they wind up on the ground and then make their way to a regulated surface water, there is a “point source” discharge that is subject to regulation under the Clean Water Act. 

Rose Acre contends that the DENR’s argument is a post hoc rationalization, without any supporting, credible evidence, to defend its decision to issue the NPDES permit.  In this regard, Rose Acre notes that the ventilation fans in question “are pointed at a ninety degree angle away from a storm water retention pond that is located over one-fifth of a mile away.”  Judge Elkin found that the stormwater pond point source theory was unsupported by the record.  Relying on the holding in National Pork Producers Council that a CAFO is not required to apply for a NPDES permit until there is an “actual discharge into navigable waters to trigger the CWA’s requirements”, Rose Acre contends that the DENR has failed to present any proof of such a discharge. 

If the Rose Acre case proceeds to ruling after the ordered full evidentiary hearing, it will be worth watching to see whether the ultimate decision is based on what’s in the air or what’s in the water (and how it got there).
