EPA & USCG Coordination to Enforce Vessel General Permit Program.

U.S. Environmental Protection Agency (EPA) and U.S. Coast Guard (USCG) today signed a memorandum of understanding (MOU) to work together to enforce EPA’s vessel general permit program. The MOU outlines steps the agencies will take to better coordinate efforts to prevent and enforce against illegal discharges of pollutants from vessels, such as cruise ships and oil tankers.

Under the MOU, USCG has agreed to incorporate components of EPA’s vessel general permit program into its existing inspection protocols and procedures to help the United States address vessel pollution in U.S. waters. The MOU creates a framework for improving EPA and USCG cooperation on data tracking, training, monitoring, enforcement and industry outreach. The agencies have also agreed to improve existing data requirements so that information on potential violations observed during inspections can be sent to EPA for evaluation and follow-up.

The vessel permit program applies to more than 61,000 commercial ships based in the U.S. and more than 8,000 foreign ships operating in U.S. waters. The vessel permit covers 26 types of discharges such as deck run-off from rain, ballast water used to stabilize ships, and wastewater from showers, sinks and laundry machines. These discharges may result in negative impacts on the environment, including the spread of invasive species from ballast water that can harm sensitive ecosystems. The vessel permit program also specifies corrective actions, self inspections and self monitoring, record keeping and reporting requirements.

ANPR For San Francisco Bay Delta Estuary Water Quality Improvements

U.S. Environmental Protection Agency has released an Advanced Notice of Proposed Rulemaking (ANPR) seeking public input on the effectiveness of current water quality programs influencing the health of the San Francisco Bay Delta Estuary. The ANPR identifies water quality issues affecting Bay Delta fisheries, describes regulatory measures currently underway, and initiates an information-gathering process on how the EPA and the State of California can achieve water quality and aquatic resource protection goals.

The ANPR is part of a set of actions to address California water issues under the Interim Federal Action Plan released in December 2009. Through this plan, the EPA has promoted water conservation and efficiency improvements throughout California, dedicated more than $40 million to drought relief projects, and to modernizing California’s water infrastructure.

EPA will be coordinating its review of water quality issues with the on-going development of the Bay Delta Conservation Plan, which currently is being developed through a collaboration of federal, state and local agencies, environmental organizations, and other interested parties.

The ANPR identifies specific issues for which the EPA has regulatory responsibility and solicits comment on topics, such as potential site-specific water quality standards and site-specific changes to pesticide regulation. Summaries describing environmental stressors and the regulatory framework necessary to address them are also included in the ANPR.

Oregon DEQ General Permit For Pesticide Application

The Oregon Department of Environmental Quality (DEQ) has released and has requested public comments on its proposed National Pollutant Discharge Elimination System (NPDES) pesticide general permit. The proposed permit is in response to the January 2009 Sixth Circuit Court ruling that NPDES permits are required for all biological and chemical pesticide applications that leave a residue or excess pesticide in water when the applications are made in, over or near water. The court required permits to be effective no later than April 9, 2011.

DEQ has proposed to issue the general permit for the following pesticide applications:

  1. Mosquito and other flying insect pest control
  2. Weed and Algae Control for invasive or other nuisance weeds, algae and pathogens in water and at the water’s edge.
  3. Nuisance Animal Control for the control of invasive or other nuisance animals and pathogens in water and at the water’s edge.
  4. Forest Canopy Pest Control for the control of pest species by using aerial application of a pesticide over a forest environment or from the ground.
  5. Area-Wide Pest Control for the control of pest species by using aerial pesticide application to cover a large area to avoid substantial and widespread economic and social impact.

The permit, once finalized, may affect both public and private entities that use pesticides for the types of pesticide applications listed above.

Operators who conduct pesticide applications above an annual threshold will need to register with DEQ. The Annual Treatment Area Thresholds proposed are:

Mosquitoes and Other Flying Insect Pests - 6,400 acres of treatment surface area
Weed and Algae Control (Excludes irrigation districts formed under ORS 545)
In Water - 20 acres of surface treatment area
In Water and at Water’s Edge: - 50 linear miles of treatment area.
Nuisance Animal Control:
In Water - 20 acres of treatment surface area
In Water and at Water’s Edge - 50 linear miles of treatment surface area.
Forest Canopy Pest Control - 6,400 acres of treatment surface area
Area Wide Pest Control - 6,400 acres of treatment surface area.

The draft permit requires all operators to minimize pesticide discharges by:

• using the optimal amount of pesticide
• preventing leaks and spills
• calibrating equipment
• use integrated pest management
• minimize the discharge of pesticides
• meet water quality standards
• maintain certain records
• report adverse incidents

Operator are also required to notify private and domestic drinking water users prior to the use of pesticides that have potable water use restrictions. All operators are required to conduct site monitoring and visual monitoring to ensure that pesticide use is minimized.

The permit sets a threshold that requires the largest pesticide users under each type of pest control to:

• submit an application for registration and pay fees
• implement integrated pest management
• develop a pesticide discharge management plan
• submit annual reports

DEQ Rulemaking On Human Health Based Water Quality Criteria

The Oregon Department of Environmental Quality is proposing rulemaking, to revise the water quality standards regulation to address the human health criteria for toxic pollutants. DEQ also has proposed to adopt new and revised water quality standards rules on implementing water quality standards through various water quality control programs, including National Pollutant Discharge Elimination System (NPDES) permits and nonpoint source pollution programs.

DEQ’s currently effective human health toxics criteria are based on a fish consumption rate that US EPA does not believe provides adequate protection for the amount of fish and shellfish consumed by Oregon residents. On June 1, 2010, EPA disapproved human health toxics criteria which Oregon submitted for approval in 2004 and which were based on a fish consumption rate of 17.5 grams per day. EPA disapproved the human health toxics criteria because the fish consumption rate is not considered protective of many Oregonians. DEQ is addressing EPA’s disapproval by proposing to use a higher fish consumption rate of 175 g/day to calculate more protective human health toxics criteria. If DEQ does not establish revised criteria, EPA must conduct rulemaking to develop human health toxics criteria for Oregon.

The proposed rulemaking also proposes new rule language and revisions to existing rule language for various NPDES permit implementation tools developed to assist dischargers in complying with revised standards. Revisions to the water quality standards and Total Maximum Daily Load (TMDL) rules are also intended to make DEQ’s rules consistent with state statutes affecting nonpoint sources of pollution and for DEQ to assign pollution load allocations to significant land and air sources in TMDLs.

Arsenic Standards and Arsenic Reduction Plan Revised by ODEQ

The Oregon Department of Environmental Quality (DEQ) is proposing to change Oregon’s water quality standards for arsenic. Public comments on the proposed change are due by February 23, 2011. The proposal revises criteria established to protect human health and adds a requirement for certain wastewater dischargers to develop Arsenic Reduction Plans.

DEQ originally proposed revisions to the state’s arsenic, iron and manganese standards for public comment in August 2010. DEQ subsequently revised the proposed arsenic criteria based on comments received. DEQ has reopening public comment and is requesting public comment on the revised proposed arsenic criteria. The Oregon Environmental Quality Commission adopted the iron and manganese standards revisions in December 2010.
