EPA Releases Draft NPDES Pesticide General Permit for Discharges
On January 26, 2016, the U.S. Environmental Protection Agency (EPA) published its draft National Pollutant Discharge Elimination System (NPDES) General Permit for Discharges from the Application of Pesticides in the Federal Register, which applies to discharges of pesticides to waters of the United States. EPA is requesting comments on the draft permit by March 11, 2016. This draft 2016 pesticide general permit (PGP) is largely an updated version of the 2011 PGP, which will expire on October 31, 2016. EPA’s permit would apply to Maine, New Hampshire, New Mexico, Idaho, and the District of Columbia; Puerto Rico and certain other territories; as well as Indian lands and federal facilities in other states that are covered by state-developed PGPs. Separately, 46 states must update their existing permits, and some states have already begun this process or have already reissued permits within the last year.
The draft 2016 PGP retains coverage of the previous pesticide use patterns (mosquito/flying insect; weed and algae; animal pest; and forest canopy), and leaves unchanged the reliance on technology-based effluent limitations (TBELs) to satisfy permit requirements, which require proper maintenance and calibration of equipment along with visual inspections to minimize discharges and meet water quality standards and Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) label requirements. The draft 2016 PGP also retains the distinctions in compliance requirements of “For-hire Applicators” and “Decision Makers,” and includes the same requirements for recordkeeping and reporting of adverse incidents. The draft permit now mandates electronic reporting, which will make Notice of Intent (NOI) and Annual Report submissions public on EPA’s e-reporting website. The draft permit retains the “joint and several liability” provision that would extend potential legal risks to all parties involved in decision-making and application of pesticides. In spite of the lack of new or altered provisions, there are some aspects of the draft 2016 PGP that could signal an EPA policy change going forward, and could potentially appear in the final version of the permit. These areas include:
- Absence of a definition for “Waters of the U.S.,” which could create confusion as to the scope of jurisdiction;
- An ongoing Endangered Species Act (ESA) consultation, which could expand the list of requirements included in the final permit;
- Request for comments on whether water quality-based effluent limitations (WQBELs), such as water quality monitoring and fish tissue testing (i.e., laboratory studies), should be included in the final permit;
- Request for comments on whether additional information should be included in NOI submissions, including whether the treatment area includes a source water for public drinking water supplies; and
- An expanded discussion of required compliance with all other applicable state and federal laws, including FIFRA storage and handling requirements, which could be perceived to attach Clean Water Act liability to a PGP permittee’s violations of FIFRA and other laws.
