Ninth Circuit Impairs NPDES Permitting  

Feb/March 2008

Environmental decisions from the Ninth Circuit are almost always interesting, though often short-lived. 1  The court’s recent decision interpreting NPDES requirements2  is a showstopper for its far reaching implications for prospective permittees, and water quality improvement efforts. The decision involves Arizona’s own Carlota Copper project, but it is not just about mining (although it certainly attests to the potential difficulties in permitting a new hard rock mine in the United States). It poses an enormous roadblock to many new dischargers in the Ninth Circuit (which includes Arizona), and possibly beyond.

Carlota’s project involves construction of an open pit copper mine near Miami, Arizona, with associated processing facilities, and waste rock piles. Carlota’s quest to obtain regulatory approvals for the project began over a decade ago, and has involved an alphabet soup of regulatory agencies and environmental decision documents, including ADEQ, EPA, USFS, ACOE, EIS,3  EA,4  TMDL,5  SEA,6  ROD, FONSI,7  EAB and SSS,9  as well as a who’s who phalanx of anti-mining extremist groups.10 

In the NPDES subplot to the saga, Carlota sought to obtain permit coverage for storm-water runoff from its waste rock piles, a type of discharge routinely covered by a general permit for industrial storm-water (e.g. MSGP 2005).11  However, early in the process (ca. 1997!), Carlota reluctantly acceded to EPA’s request to apply for an individual permit. EPA’s concerns stemmed in part from the fact that Pinto Creek had been designated as "impaired" for copper, due primarily to discharges from abandoned mines in the drainage, including the "Gibson Mine" site. 12 

EPA’s permit regulations include a provision restricting the issuance of permits for new discharges to a water not meeting applicable water quality standards, which states:

No permit may be issued:

***

(i) To a new source or a new discharger, if the discharge from its construction or operation will cause or contribute to the violation of water quality standards. The owner or operator of a new source or new discharger proposing to discharge into a water segment which does not meet applicable water quality standards … and for which the State … has performed a pollutants load allocation for the pollutant to be discharged, must demonstrate, before the close of the public comment period, that:

(1) There are sufficient remaining pollutant load allocations to allow for the discharge; and

(2) The existing dischargers into that segment are subject to compliance schedules designed to bring the segment into compliance with applicable water quality standards.13 

Carlota and EPA agreed to include a special condition in Carlota’s NPDES permit whereby Carlota would be required to undertake a cleanup project at the Gibson Mine prior to discharging from its operations. The project was designed to substantially improve runoff from the Gibson Mine site, and water quality in Pinto Creek, by removing the identified major sources of copper contamination in the drainage. The water quality benefits of this project are projected to dwarf any pollutant contribution of Carlota’s operations, thereby "offsetting" the discharges allowed by its permit.

Under the offset concept, Carlota’s discharge would not be construed as "causing or contributing" to the impairment of the receiving water, rendering the remainder of the regulation (load allocations and compliance schedules) inapplicable. This approach is consistent with EPA’s longstanding interpretation of its own regulations, and is designed to encourage innovative approaches to improving water quality, while allowing discharges with a net-positive water quality impact. The NPDES permit was issued in July, 2000.

The NGOs challenged the permit at every juncture, first forcing the permit to be withdrawn while the agencies undertook additional assessment, and then challenging it before the Environmental Appeals Board after EPA reissued the permit in February, 2002. (Ironically, the ongoing NGO challenges delayed for many years the cleanup of the acknowledged major source of contamination in the drainage at the Gibson Mine, and the water quality improvements provided for in the permit). The EAB issued an exhaustive decision in 2004 upholding the permit, which was then followed by the subject appeal to the Ninth Circuit.

Before the Ninth Circuit, EPA and Carlota argued that the 122.4(i) restrictions were not applicable because Carlota’s operation would not "cause or contribute" to the impairment given the offset provided by the Gibson Mine cleanup condition.14  EPA/Carlota also argued that even if the restrictions applied, the conditions were met because the TMDL study EPA completed includes sufficient load allocations to allow Pinto Creek to meet applicable water quality standards, and because EPA had included appropriate discharge limitations in the permits it had issued to other discharges along the creek.

The three judge panel of the Ninth Circuit15  rebuffed EPA/Carlota at every turn, concluding that the 122.4(i) restrictions prohibit any quantity of discharge from a new source/new discharge to an impaired water whatsoever, regardless of any offsets, unless a TMDL has been performed demonstrating load allocations will be met (query how exactly an agency could make such a demonstration), and EPA has imposed at least "compliance schedules" on all dischargers to the impaired water (not just permitted, point sources).16  In doing so, the court accorded absolutely no deference to EPA’s interpretations of its own regulations, and in fact did not so much as mention this well-accepted principle of judicial review.

The Carlota court’s interpretation of the 122.4(i) discharge restriction, if it survives appeal, may effectively prohibit the issuance of NDPES permits, including general permit authorizations, to new dischargers on impaired waters. The § 122.4(i) restriction applies to state NPDES program, including Arizona’s,17  and thus the decision could affect NPDES programs beyond those in the Ninth Circuit. As in most states, Arizona has many water segments not meeting applicable standards (over 100), and the process of developing TMDLs takes years due to, among other factors, the challenges of gathering sufficient data in a desert environment. This fact is aptly illustrated by Pinto Creek, where the TMDL process has been ongoing for over 10 years. The process of developing "compliance schedules" for every discharger on an impaired segment, as mandated by the Carlota court, could take many more years, and in fact may not be possible under NPDES authorities, which extends to point sources, but not non-point sources.

The decision could be broader still if construed to apply to all types of new point source discharges (process- and storm-water), including storm-water from construction projects. The decision also severely undermines any incentive for prospective permittees to undertake innovative offset projects to improve water quality (such as Carlota has done at the Gibson Mine), which will have a detrimental impact on water quality. Prospective new dischargers impacting impaired segments would be left to engineer facilities to a "no discharge" standard (rarely a guarantee, due to the potential for floods or malfunctions/breakdowns, etc.), hope for extraordinary agency efforts to develop the requisite TMDLs and compliance schedules for all dischargers (often a practical impossibility due to budgetary and workload realities), move the project elsewhere, or abandon it altogether.

Carlota filed a petition for rehearing with the Ninth Circuit on January 18, 2008, but the Department of Justice (on behalf of EPA), in another surprising development, unfortunately declined to file its own petition. Amicus briefs are due February 5, 2008 (after this article went to press), and at least a few stakeholder groups should file in support of Carlota, given the drastic and far reaching impacts of the decision. We can expect to hear this Spring as to whether the full Ninth Circuit will reconsider the case, or Carlota will be left with a last resort petition to the Supreme Court.

11 Carlota’s storm-water retention basins would contain either the 10-year/24-hour or 100-year/24-hour storm event, so discharges would only occur during larger rain events.

12 After further study, ADEQ has since concluded (too late for purposes of this case, as Carlota’s bad luck would have it) that Pinto Creek would not meet applicable water quality standards due to natural background conditions alone, and recently proposed a higher "site specific" copper standard for Pinto Creek to reflect natural conditions.
