New Discharge Monitoring Report (DMR) Pollutant Loading Tool

The U.S. Environmental Protection Agency (EPA) has released a new tool that provides the public with information about discharges into local waterways. The Discharge Monitoring Report (DMR) Pollutant Loading Tool brings together millions of records and allows for searching and mapping of water discharges by local area, watershed, company, industry sector, and pollutant.

Searches using the DMR Pollutant Loading Tool result in “top ten” lists to help users identify facilities and industries that are discharging the most pollutants and impacted waterbodies. When discharges are above permitted levels, users can view the violations and link to details about enforcement actions that EPA and states have taken to address these violations.

A link to the new tool can be found on EPA’s Enforcement and Compliance History Online (ECHO) website, which provides information about inspections, facility compliance, and state and federal enforcement actions. EPA has also released several new ECHO features, including a search for criminal enforcement cases and web developer tools for ECHO reports and maps.

Minnesota Agricultural Water Quality Certification Program AWQCP Agreement Signed

The US Environmental Protection Agency (EPA) and US Department of Agriculture (USDA) have signed a Memorandum of Understanding (MOU) with the state of Minnesota to develop a new state program for farmers designed to increase the voluntary adoption of conservation practices designed to protect local rivers, streams and other waters by reducing fertilizer run-off and soil erosion. USDA and EPA will offer support to Minnesota in developing “certainty agreements” for water quality improvements on private agricultural lands and eligible tribal lands in high priority watersheds.

The MOU signing is the first step toward developing the Minnesota Agricultural Water Quality Certification Program (AWQCP), designed to increase the adoption of recommended conservation practices to improve water quality on agricultural land. The MOU signing formalizes the state-federal partnership and confirms a joint commitment to developing and implementing the program. Minnesota and its partners will establish a Technical Advisory Committee to develop the certification program that will support the state’s water quality standards and goals. The committee will solicit input from stakeholders in designing criteria to provide certainty for producers who have voluntarily attained or maintained a certain level of water quality improvements on their agricultural land. Minnesota will test the program in several pilot watersheds.

EPA Approves Some and Disapproves Other Proposed Changes To Iowa Designated Uses

EPA has approved the Iowa Department of Natural Resources’ (IDNR) designated use changes for 430 water bodies and disapproved proposed changes for 89 water bodies. Designated uses describe the achievable recreational activities and aquatic life uses for Iowa’s waters.

IDNR submitted these new and revised Iowa surface water quality standards to EPA for review and approval, as required by the Clean Water Act (CWA). The state based its recommendations on site-specific field data gathered by IDNR in and near streams, lakes and rivers. This submission updates the use designations to determine the highest attainable use for the individual waters. Designated recreational uses protect for activities such as swimming, fishing and canoeing; and for human consumption of aquatic life. Aquatic life uses provide for the protection and maintenance of a healthy environment for fish and other animals.

Draft Vessel Permits For Large & Small Commercial Vessels

U.S. Environmental Protection Agency (EPA) is issuing two draft vessel general permits that would regulate discharges from commercial vessels, excluding military and recreational vessels. The proposed permits are intended to protect the nation’s waters from ship-borne pollutants and reduce the risk of introduction of invasive species from ballast water discharges.

The draft Vessel General Permit, which covers commercial vessels greater than 79 feet in length, would replace the current 2008 Vessel General Permit, when it expires in December 2013. The new draft Small Vessel General Permit would cover vessels smaller than 79 feet in length and would provide such vessels with the Clean Water Act permit coverage they will be required to have as of December 2013.

Both permits will be subject to a 75-day public comment period. EPA intends to issue the final permits in November 2012 to allow vessel owners and operators time to prepare for new permit requirements.

Summary of Draft Vessel General Permit:
The updated permit would reduce the administrative burden for vessel owners and operators, eliminating duplicative reporting requirements, clarifying that electronic recordkeeping may be used instead of paper records, and streamlining self-inspection requirements for vessels that are out of service for extended periods. The permit would continue to regulate the 26 specific discharge categories that were contained in the 2008 permit and, for the first time, manage the discharge of fish hold effluent.

A key new provision of the permit is a proposed numeric standard to control the release of non-indigenous invasive species in ballast water discharges. The new ballast water discharge standard addressing invasive species is based upon results from independent EPA Science Advisory Board and National Research Council National Academy of Sciences studies. These limits are generally consistent with those contained in the International Maritime Organization’s 2004 Ballast Water Convention. The new standard is expected to substantially reduce the risk of introduction and establishment of non-indigenous invasive species in U.S. waters.

The draft Vessel General Permit also contains updated conditions for mechanical systems that may leak lubricants into the water and exhaust gas scrubber washwater, which would reduce the amount of oil and other pollutants that enter U.S. waters. EPA will take comment on potentially more stringent requirements for bilgewater discharges.

Summary of Draft Small Vessel General Permit:
This permit would be the first under the Clean Water Act to address discharges incidental to the normal operation of commercial vessels less than 79 feet in length. Recognizing that small commercial vessels are substantially different in how they operate than their larger counterparts, the draft Small Vessel General Permit is shorter and simpler. The draft permit specifies best management practices for several broad discharge management categories including fuel management, engine and oil control, solid and liquid maintenance, graywater management, fish hold effluent management and ballast water management, which consists of common sense management measures to reduce the risk of spreading invasive species. The permit would go into effect at the conclusion of a current moratorium enacted by Congress that exempts all incidental discharges from such vessels, with the exception of ballast water, from having to obtain a permit until December 18, 2013.

Streamflow Duration Assessment Method For Section 404 Compliance

Section 404 of the federal Clean Water Act and Oregon’s Removal-Fill Law require permits to protect water resources when someone plans to place soil, dredged or other material in regulated waters. The task of determining if a particular stream is protected under federal and state fill and disposal regulations has become a little easier. The new Streamflow Duration Assessment Method for Oregon will help natural resource professionals, consultants and regulators identify whether a fill or removal project with potential stream impacts must obtain permits.

This new method provides a consistent, repeatable and quick way to identify whether an Oregon stream is intermittent, perennial or ephemeral. Intermittent streams, which flow seasonally, and perennial streams, which flow continuously, are typically subject to both state and federal regulations. Ephemeral streams only flow after rainfall or during snowmelt, and under current agency practice are protected under the Clean Water Act if they have a significant effect on the integrity of larger downstream waters.

The tool was released in November after a two-year trial run. The method was tested and refined at over 170 sites in western and eastern Oregon during both the wet and dry seasons. The method proved accurate in many environments including natural, modified and braided channels. It is a scientific tool that is useful anytime the duration of streamflow must be determined, and may help identify other stream-related issues. Because of the demonstrated benefit in Oregon, the method is already being adapted for use in Idaho and Washington.
