City of Stockton and County of San Joaquin Page 51 <br /> NPDES Permit CAS0083470 <br /> Response to Comments <br /> Through the iterative process set forth in the Tentative Order, as stated above, each Permittee is <br /> required to timely implement control measures and other actions to reduce pollutants in the <br /> discharge to the MEP in accordance with the SWMP. If exceedances of water quality standards <br /> persist,the Permittees are required to assure compliance through a process whereby they submit a <br /> Report of Water Quality Exceedance (RWQE) that describes currently implemented BMPs and <br /> additional BMPs that will be implemented to prevent or reduce the exceedances. The RWQE must <br /> include a monitoring program, a rationale for the new BMPs, a discussion of the expected pollutant <br /> reductions and how implementation of the BMPs will prevent future water quality standard <br /> exceedances. In addition, the RWQE must include an imiplementaion schedule, with milestones <br /> and performance standards. (See Tentative Permit, Provision D.1.) <br /> 10. Comment: (DK Comment 2(f)(1))the Permit must contain compliance schedules. <br /> Finding 33 states that"[i]t is not feasible at this time, to establish numeric effluent limits for <br /> pollutants in storm water discharged from MS-4s. Therefore effluent limitations are narrative and <br /> include the requirement to reduce pollutants in storm water discharges to the MEP," and <br /> "[i]mplementation of performance standards and BMPs in accordance with the Permittees' SWMP <br /> and their schedules constitutes compliance with MEP requirements, and with requirements to <br /> achieve water quality objectives" <br /> Staff has provided no substantive evidence that numeric limitations are"infeasible" as required by <br /> EPA regulations. Since the state clearly has the statutory authority to require numeric limitations if <br /> it elects to do so, it is not acceptable to simply declare that numeric limitations are infeasible. There <br /> must be substantial evidence in the Findings and Fact Sheet to support the claim. <br /> Finding 26 states that"[t]his Order shall ensure compliance with water quality standards. This <br /> Order, therefore, includes requirements to the effect that discharges shall not cause or contribute to <br /> violations of water quality standards that would cause or create a condition of nuisance,pollution, or <br /> water quality impairment in receiving waters. Accordingly, the Regional Board is requiring that <br /> these requirements be addressed through the effective implementation of Best Management <br /> Practices (BMPs)to reduce pollutants in storm water." <br /> As we established above, this Finding never escapes the realm of wishfully fantasy. The is no nexus <br /> between the Permit's performance standards and BMPs and reductions in contaminate loadings or <br /> attainment of water quality standards,which, as of this writing, are being exceeded. A performance <br /> standard cannot simply be a measure of implementing a given BMP that may or may not have a <br /> reasonable expectation of improving water quality. A performance standard must be the measure of <br /> a given BMPs effectiveness in actually reducing impairment. There must be substantial evidence in <br /> the Findings and Fact Sheet to support the claim that the BMPs and performance standards in the <br /> Permit are likely to be successful in achieving compliance with water quality standards. <br /> The boilerplate approach of iterative BMP implementation violates the CWA requirement that <br /> storm water permits must comply with their required terms within 3 years after the date of issuance <br /> of the permit. 33 USC § 1342(p)(4) &(5). The Regional Board's use of EPA's interim permitting <br /> approach clearly conflicts with the statutory deadline. <br />
