- Registration Open for Listening Session on Chesapeake Bay Requirements in EPA's Proposed Stormwater Rulemaking - In a Federal Register Notice published on October 8, 2010, EPA informed the public of its preliminary considerations for modifying or supplementing EPA's stormwater regulations to specifically address stormwater discharges in the Chesapeake Bay watershed and solicited public input on these considerations. Five public listening sessions are being held across the Bay watershed in October-November 2010. These public listening sessions afford an opportunity for the public to provide input on regulatory actions that EPA is considering. A webcast is also being offered and is intended as a 'virtual' listening session for those unable to participate in one of the five listening sessions. Dates and locations available on the NPDES Training Courses and Workshops webpage.
September 30, 2010
- Permit Writers Manual - Revised edition of the U.S. EPA NPDES Permit Writers' Manual (EPA-833-K-10-001), which provides a comprehensive overview of the basic framework of the National Pollutant Discharge Elimination System (NPDES) program and serves as a principal training tool for new state and EPA permit writers. The revised NPDES Permit Writers' Manual has been thoroughly reviewed and updated to reflect current policy and guidance, address changes to the NPDES program, and include discussions of new EPA program areas, such as the Stormwater Phase II Rule, concentrated animal feeding operations, cooling water intake structures [i.e., Clean Water Act Section 316(b)], pesticide applications, and vessel discharges.
June 23, 2010
- Proposed Sufficiently Sensitive Methods Rulemaking - EPA is proposing minor amendments to its CWA regulations to codify that under the NPDES program, only "sufficiently sensitive" analytical test methods can be used when completing an NPDES permit application and when performing sampling and analysis pursuant to monitoring requirements in an NPDES permit.
June 02, 2010
- Pesticide General Permit for Discharges from the Application of Pesticides - On June 2, 2010, EPA announced the public availability of a draft National Pollutant Discharge Elimination System (NPDES) permit for point source discharges from the application of pesticides to waters of the United States. This permit is also known as the Pesticides General Permit (PGP). The PGP was developed in response to a decision by the Sixth Circuit Court of Appeals (National Cotton Council, et al. v. EPA).
March 01, 2010
- Draft Vessels Report to Congress: Study of Discharges Incidental to Normal Operation of Commercial Fishing Vessels and Other Non-Recreational Vessels Less than 79 Feet - This study was conducted to meet the obligations of EPA under Public Law (P.L.) 110-299 (July 31, 2008). The law provided for a two-year moratorium on National Pollutant Discharge Elimination System (NPDES) permitting of discharges from commercial fishing vessels, regardless of size, and other non-recreational vessels less than 79-feet long that were subject to the 40 CFR 122.3(a) exclusion. This draft report summarizes the primary pollutant concentrations in the discharges sampled and evaluates the potential environmental impact of these discharges on large water bodies.
February 19, 2009
February 18, 2009
- MSGP SWPPP Guidance - A guidance on how to develop a SWPPP (Stormwater Pollution Prevention Plan) that meets the requirements of the 2008 MSGP (Multi-Sector General Permit) is now available.
January 08, 2009
- Final Rule on Aquatic Pesticides Vacated - On January 7, 2009 the 6th Circuit Court of Appeals issued an opinion that vacated EPA’s final rule "Application of Pesticides to Waters of the United States in Compliance with FIFRA." The Agency is reviewing the court’s opinion and considering next steps.
January 08, 2009
December 18, 2008
- Final 2008 Vessel General Permit - On December 18, EPA issued a final Vessel General Permit (VGP) to reduce releases of 26 types of discharges from vessels operating in U.S. waters. Beginning December 19, approximately 61,000 domestically flagged commercial vessels and 8,000 foreign flagged vessels will need to comply with the permit. The permit covers non-recreational vessels 79 feet in length or longer, such as cruise ships or oil and cargo tankers, but excludes fishing vessels of any length, unless they discharge ballast water. The new permit incorporates the Coast Guard’s mandatory ballast water management and exchange standards, and provides technology-based and water-quality-based effluent limits for other types of discharges, including deck runoff from rain or cleaning, ballast water used to stabilize ships and “gray water” from showers, sinks and laundry machines. It also establishes specific corrective actions, inspections and monitoring, recordkeeping and reporting requirements.
October 31, 2008
- 2008 CAFO Regulations - Revised regulations that address the Second Circuit court’s 2005 decision in Waterkeeper Alliance et al. v. EPA, 399 F.3d 486, were signed on October 31, 2008. These regulations will become effective on December 22, 2008. The final rule responds to the Waterkeeper decision that upheld most of EPA's 2003 rule, but directed further action or clarification on some portions.
September 23, 2008
- Final 2008 Multi-Sector General Permit - The new Stormwater Multi-Sector General Permit (MSGP) covers an estimated 4,100 industrial facilities that require NPDES permit coverage. EPA’s MSGP applies to facilities in states and territories not authorized to implement the NPDES permit program, including Alaska, Idaho, Massachusetts, New Hampshire, New Mexico, most U.S. territories, most Indian country lands, and several other locations. The new permit offers several improvements from the previous MSGP, including easy to understand discharge requirements; fast and easy electronic filing of Notices of Intent (NOIs) and monitoring reports; and several new web-based tools.
July 01, 2008
- Final 2008 Construction General Permit - On June 30, EPA issued a final 2008 Construction General Permit (CGP) that covers discharges of stormwater from certain construction sites. Because EPA is in the process of developing a national regulation (called an Effluent Limitations Guideline) for the construction and development industry, this permit contains substantially the same terms and conditions as the 2003 CGP and has been issued for a two-year time period. The new permit applies only to “new” construction sites (e.g., those that have started construction on or after June 30, 2008 or those that started previously, but did not obtain permit coverage under the 2003 CGP).
June 16, 2008
- Proposed Vessel Discharges General Permits - EPA is soliciting public comment on two proposed NPDES vessel permits, the Vessel General Permit (VGP) for Commercial and Large Recreational Vessels (79 feet or longer) and the Recreational General Permit (RGP) (recreational and uninspected passenger vessels less than 79 feet in length). The public comment period will be open for 45 days.
June 02, 2008
- Water Transfers Final Rule - EPA is publishing a final rule to exclude water transfers from the NPDES permitting program. The Agency believes that Congress intended for water transfers to be subject to oversight by water resource management agencies and State non-NPDES authorities, rather than the NPDES permitting program. The final rule defines a water transfer as an activity that conveys or connects waters of the United States without subjecting the transferred water to intervening industrial, municipal, or commercial use. This does not apply to pollutants introduced by the water transfer activity itself to the water being transferred.
May 27, 2008
May 15, 2008
- Proposed 2008 Construction General Permit (CGP) - EPA has issued a proposed 2008 Construction General Permit (CGP) for public comment. This public comment period will close on June 16, 2008. The 2008 CGP applies to discharges of stormwater from construction sites that disturb 1 acre or more of land, and from smaller sites that are part of a larger, common plan of development. Because EPA is also in the process of developing a national regulation (called an Effluent Limitations Guideline) for the construction and development industry, the Agency is proposing to issue this 2008 CGP for a period of two years and using the same terms and conditions as the 2003 CGP (which expires on July 1, 2008). Upon completion of the Effluent Guideline, the Agency will develop and issue a new (and improved) CGP that incorporates the provisions of the Effluent Guideline as soon as possible and not later than July 2010.
January 25, 2008
- Low Erosivity Waiver (LEW) Calculator - Some state construction general permits allow construction operators in more arid climates to apply for a waiver from NPDES permitting requirements. EPA has developed the LEW calculator to help small construction sites determine whether they qualify for this waiver. The calculator provides assistance to operators estimating the rainfall erosivity factor (R factor) to determine whether the R factor is low enough to justify a waiver from NPDES permitting requirements. The R factor can easily be calculated by using the construction site latitude/longitude or address and estimated start and end dates of construction. NOTE: Authorized states might have requirements different from EPA’s, and you should review your general permit for specific requirements.
January 17, 2008
- Green Infrastructure Action Strategy - Developed by the Partners for Green Infrastructure (American Rivers, Association of State and Interstate Water Pollution Control Administrators, Low Impact Development Center, National Association of Clean Water Agencies, Natural Resources Defense Council, and EPA) this Action Strategy details a wide variety of efforts that will be pursued over the years by the partner organizations to reduce stormwater runoff, combined sewer overflows, and nonpoint source pollution. The Action Strategy covers seven broad categories, including research, outreach, demonstration projects, and more.
January 09, 2008
- Urban BMP Performance Tool - This tool has been developed to provide
stormwater professionals with easy access to approximately 220 studies
assessing the performance of over 275 BMPs. The tool provides access to
studies covering a variety of traditional and low impact BMP types,
including retention and detention ponds, biofilters, grassed filter
strips, porous pavement, wetlands, and others. Users will also find a
series of essays aimed at improving understanding of BMP performance and
the importance of volume reduction/infiltration in these assessments. EPA plans to add more studies to this tool over the coming year,
focusing on expanding the collection of studies of low impact
development or green infrastructure BMPs.

The extension is in response to changes required by the Second Circuit Court of Appeals decision in Waterkeeper Alliance et al. v. EPA.
June 20, 2007
- EPA Developing Vessel Discharge Permit Program - EPA is seeking information as it considers how to develop a water permit program for pollutant discharges incidental to the normal operation of commercial vessels and recreational boats. Vessel owners or operators whose discharges previously have been exempt from CWA requirements will require a permit beginning September 30, 2008. Regulated discharges may include ballast water, bilge water, deck runoff, and gray water. EPA is seeking public comments and data to help the agency develop the permitting framework. Specifically, EPA is seeking information about vessel identification and operations, owner notification, discharge impacts, pollution control equipment and practices, and commercial and recreational vessel traffic patterns. Comments and data are due within 45 days of publication of the notice in the Federal Register.
May 04, 2007
- Proposed Extension of Compliance Dates for CAFO Rule – EPA proposes a second extension to certain compliance dates in the NPDES permitting requirements and Effluent Limitations Guidelines (ELGs) for CAFOs. The extension is in response to changes required by the Second Circuit Court of Appeals decision in Waterkeeper Alliance et al. v. EPA. This proposed rule will be open for a 30-day comment period closing on June 11, 2007.

The statement of intent pledges cooperation among these groups to promote the use of various green infrastructure techniques such as rain gardens, bioretention cells, infiltration swales, green parking lot design, rain barrels, and many others. Today's agreement supplements an early statement supporting green infrastructure that has been signed by over 30 national groups.
March 28, 2007
November 21, 2006
- Application of Pesticides to Waters of the United States in Compliance with FIFRA: Final Rule - A new rule clarifies that a NPDES permit will not be required when application of a particular pesticide to or over, including near, waters of the United States is consistent with requirements of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). The rule identifies two specific circumstances where NPDES permits are not required: the application of pesticides directly to water in order to control pests; and the application of pesticides to control pests that are present over or near water, where a portion of the pesticides will unavoidably be deposited to the water in order to target the pests.
July 21, 2006
June 22, 2006
- Proposed Revisions to CAFO NPDES Rule - EPA seeks comments on proposed revisions to the NPDES and Effluent Limitation Guidelines for CAFOs. The proposed rulemaking is in response to the order issued in Waterkeeper Alliance et al. v. EPA, (2nd Cir. 2005). Comments are due for this proposed rule by August 14, 2006. See the preamble and regulatory text for details on how to comment on the revised CAFO Rule.
June 07, 2006
June 01, 2006
- Proposed Water Transfers Rule - EPA is proposing a rule to exclude water transfers from the NPDES permitting program. The proposed rule would define a water transfer as an activity that conveys waters of the United States to another water of the United States without subjecting the water to intervening industrial, municipal, or commercial use. This exclusion does not apply, though, to pollutants that the water transfer itself may introduce to the water being transferred. The Agency believes that Congress intended for water transfers to be subject to oversight by water resource management agencies and State non-NPDES authorities, rather than the NPDES permitting program.
- The comment period has been extended until August 7, 2006.
May 24, 2006
- New and Revised National Menu of Stormwater BMPs - EPA has completed a significant revision of the National Menu of Best Management Practices (BMPs). The new menu will be easier to browse and search and includes approximately 20 new fact sheets that highlight innovative practices. We also invite knowledgeable experts in the stormwater field to provide comments and supply additional information that can improve the fact sheets contained in the Menu.
May 11, 2006
- Stormwater Qualifying Local Programs - Memorandum encouraging the further use of the Qualifying Local Programs (QLP) concept - QLP is part of the Phase II regulations that recognizes strong existing local sediment and erosion control programs, provide the opportunity to recognize other communities as they develop local sediment and erosion control programs in the future, and provide opportunities to streamline the regulatory process for construction site operators. A letter was sent to the EPA Regions and state permitting authorities to encourage the further use of this provision. This document includes a sample letter and attachment that was sent to EPA Region 1 and the state of Alabama.

- Proposed Peak Wet Weather Discharge Policy - EPA is seeking comments on a proposed policy for addressing peak wet weather events at wastewater treatment plants. The proposed policy describes the limited circumstances when certain management techniques may use to address very high flows that result from storm events. These techniques seek to ensure the continued safe operation of the treatment facility and to ensure the protection of human health and nearby waterbodies. Comments must have been received or postmarked on or before January 23, 2006.
December 01, 2005
November 02, 2005
- EPA Seeks Comments on Two Issues Concerning the Removal Credit Provisions in the General Pretreatment Regulations [PDF - 50 KB - 4 pp] - EPA is requesting public comment on whether to amend the list of pollutants for which removal credits are available to industrial dischargers. The pollutants that the Agency is requesting comments on are those that have previously passed EPA's exposure and hazard screening process. EPA is also soliciting comment on options to amend the "consistent removal" provision in the removal credits regulations to make it easier for municipalities to implement. The Agency will accept comments until December 13, 2005.
November 02, 2005
- Final Pretreatment Streamlining Rule [PDF - 408 KB - 66 pp] - On September 27, 2005, EPA signed and on October 14, 2005 published in the Federal Register final changes to its General Pretreatment Regulations.

January 27, 2005
- Application of Pesticides to Waters of the United States in Compliance with FIFRA - EPA is issuing an interpretive statement and a proposed rule in response to questions raised about Clean Water Act (CWA) permitting requirements for the application of pesticides to or over the nation's waters. The statement reflects our belief that a CWA permit is not required where application of a particular pesticide to or over water is consistent with requirements under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). However, we are reinforcing for local officials, resource managers, agricultural producers, and other pesticide users the importance of applying pesticides in accordance with their label directions. Comments on this action must have been received or postmarked on or before midnight April 4, 2005.
January 13, 2005
- EPA Proposes to Extend Permit Deadline for Stormwater Discharges from Oil and Gas Construction Activities - EPA proposed to extend the regulatory deadline that would require stormwater permit coverage for oil and gas construction activities that disturb between one and five acres of land to June 12, 2006. The additional time was used to consider comments raised by stakeholders and to consider the economic, legal, and procedural implications related to controlling stormwater discharges from these sites. The proposed extension also describes EPA's intent to develop and propose a regulation that would address stormwater discharges from these oil and gas construction sites. The public was able to provide comments on the proposed extension for oil and gas construction activities disturbing one to five acres of land for thirty (30) days from publication in the Federal Register.

- EPA Issues Draft Policy on Blending at Sewage Treatment Facilities for Public Comment - EPA has issued this draft policy to establish consistent national guidelines on the practice of blending that is used by municipal sewage treatment facilities to manage high flows associated with storm events. Already widely used, blending is a technique to manage high flows that could damage sensitive parts of the sewage treatment system or could lead to overflows of raw sewage into local waterways. The draft policy outlines safeguards and requirements to be followed during blending and restates the requirement that all discharges must continue to meet Clean Water Act permit limits. The public comment period ended on January 9, 2004.

- Waters of the U.S. Jurisdiction: ANPRM and Guidance - On January 10, 2003, the U.S. Army Corps of Engineers and EPA issued an advance notice of proposed rulemaking (ANPRM) in order to obtain early comment on issues associated with the scope of waters that are subject to the Clean Water Act (CWA) in light of the U.S. Supreme Court decision in Solid Waste Agency of Northern Cook County v. U.S. Army Corps of Engineers, 531 U.S. 159 (2001) (SWANCC). Comments in response to the ANPRM were due by March 3rd, 2003. This decision has implications for many CWA programs, including Section 404, Section 402 (NPDES), and others. The ANPRM also contains a copy of a January 10, 2003, EPA and Corps joint memorandum that provides clarifying guidance on these issues.

- Watershed-based NPDES Permitting Case Studies have arrived! - EPA has developed a series of fact sheets to highlight existing examples of watershed-based NPDES permitting throughout the country. The information contained in the fact sheets provides the context for watershed-based NPDES permitting and gives details about how the approach is used in each watershed.

- EPA Construction General Permit (CGP) - The CGP for large construction (disturbing five or more acres) for Regions 1, 2, 3, 5, 7, 8, 9, and 10 expired on February 17, 2003. EPA is in the process of developing a new permit and expects that it will be finalized in May 2003. In the interim, large construction activities are encouraged to utilize the existing Notice of Intent (NOI) form [PDF Format] and submit it to EPA (complete instructions are included in the form). Large construction activities are also encouraged to comply with the permit conditions of the expired CGP and develop Storm Water Pollution Prevention Plans and implement erosion and sedimentation controls (best management practices) on their sites. The Office of Enforcement and Compliance Assurance has made enforcement for lack of permit coverage a low priority until the new CGP is finalized.

- EPA Denies Petition Related to Ballast Water - EPA has denied a petition submitted by a number of environmental groups and other interested parties that sought to repeal provisions of EPA's regulations that cover certain discharges from vessels, including the discharge of ballast water. EPA has denied the petition for a variety
of reasons, particularly because of the wide variety of regulatory and non-regulatory actions currently being taken by other federal agencies to address the potential introduction of invasive species from discharges of ballast water. For more information, please see EPA's decision and supporting documents.

- Draft Watershed-Based NPDES Permitting Implementation Guidance is Available for Comment - Describes the concept of and the process for watershed-based permitting under the NPDES permit program. Watershed-based NPDES permitting is an approach to developing NPDES permits for multiple point sources located within a defined geographic area (i.e., watershed boundaries). This approach, aimed at achieving new efficiencies and environmental results, provides a process for considering all stressors within a hydrologically defined drainage basin or other geographic area, rather than addressing individual pollutant sources on a discharge-by-discharge basis. The public comment period [PDF Format] on this draft guidance closed September 24, 2003.

- Charge to the NPDES/Pesticides Work Group - Signed July 11, 2003 by G. Tracy Mehan, III, Assistant Administrator for Water and Stephen Johnson, Assistant Administrator for Prevention, Pesticides and Toxic Substances that directed an EPA workgroup to compare the risk management/risk mitigation measures that have been adopted as a result of the FIFRA label relative to actions that would be required as a result of an NPDES permit. It also directed the group to identify any recommendations that could be made under either FIFRA/FQPA (Food Quality Protection Act) or CWA that would assist in better coordination, integration, and increased efficiencies between the programs and continued protection of the aquatic environment. These could include modifications in the pesticide registration process or changes in the approach to risk management under the CWA and/or FIFRA.

- Interim Statement and Guidance on Application of Pesticides to Waters of the US in Compliance with FIFRA - Addresses 2 sets of circumstances for which EPA believes that the application of a pesticide to waters of the US consistent with all relevant requirements of FIFRA does not constitute the discharge of a pollutant that requires a NPDES permit under the CWA: (1) The application of pesticides directly to waters of the US in order to control pests (e.g. mosquito larvae or aquatic weeds that are present in the water) and (2) the application of pesticides to control pests that are present over waters of the US that result in a portion of the pesticide being deposited to water bodies (e.g when insecticides are aerially applied to a forest canopy where water may be present below the canopy or when insecticides are applied over water for control of adult mosquitos).

- 2003 Construction General Permit - EPA reissued its NPDES general permit for storm water discharges associated with construction activity. This permit is effective for 5 years and is available everywhere EPA is the NPDES permitting authority, except EPA Region 4. The permit provides coverage for large (>5 acres disturbed) and small (1-5 acres disturbed) construction activities, the latter being added as a result of the Phase II Storm Water Rule, promulgated on December 8, 1999. Copies of the permit and permit fact sheet, federal register announcement, background information, and procedures on how to comply with the permit are included.

- April is Stormwater Month! - A CD-based outreach kit to help communities implement the new requirements of the Phase II NPDES stormwater regulations. The kit includes a wide variety of materials for homeowners, construction site operators, children, and businesses. Local officials can use the Stormwater Month CD to customize these materials with their agency's name, address, and phone number so that citizens will know where to turn for more information.

- Postponement of the NPDES Storm Water Permit Deadline for Oil and Gas Construction Activity Disturbing 1 to 5 Acres of Land - On March 5, 2003, the Administrator signed the final rule that postpones until March 10, 2005, the NPDES storm water permit deadline for oil and gas construction activity disturbing 1 to 5 acres of land. The NPDES storm water regulations (Phase II), finalized on December 8, 1999, include coverage for such facilities. At that time, EPA believed that few of these facilities would be affected by the rule. Since that time, EPA has become aware that as many as 30,000 facilities could be affected. During the two-year postponement, EPA will analyze and evaluate this information and its potential impact.
February 13, 2003
- February is Wastewater Month! - Materials provided will assist communities in raising awareness of important wastewater issues. Local officials will find space on many of the materials to insert local contact information so citizens will know where to turn for more information.
