Here’s a small sample of some of the things we’ve been up to recently.

Municipal Stormwater Training Forums

U.S. EPA Region 3

Services: Training

EPA R3 stormwater training

Continuously since 2008, PG has supported U.S. EPA Region 3 inspectors in assessing compliance of municipal separate storm sewer system programs in the region, primarily Virginia, Maryland, Pennsylvania, and West Virginia. Recently, U.S. EPA Region 3 enhanced its compliance efforts by providing MS4 permittees with complementary training and idea-sharing opportunities. We worked with the U.S. EPA, Virginia Department of Environmental Quality, and Maryland Department of the Environment to coordinate and facilitate two MS4 training forums (including classroom and field sessions) for MS4 permittees in Virginia and Maryland. The training forums, held in 2015, collectively included more than 250 trainees comprising representatives from approximately 120 MS4 permittees.

NPDES Permits

U.S. EPA Regions and Multiple States

Services: NPDES Permitting

For over a decade, PG experts have supported U.S. EPA and states in tackling their often daunting NPDES program requirements under the Clean Water Act. We have prepared hundreds of legally defensible NPDES permits (both individual and general) spanning all types of regulated discharges (e.g., industrial/commercial wastewater, POTWs, industrial/construction stormwater, MS4s, CAFOs, vessels, SSOs, and CSOs), as well as general permits for many point source categories to help reduce permit backlog. Our NPDES permitting team has also developed innovative methods, tools, and guidance to support the U.S. EPA and states in optimizing NPDES program efficiency so they can better leverage their internal resources.

NPDES Inspections

U.S. EPA Regions and Multiple States

Services: Compliance

PG staff have unparalleled experience, having conducted thousands of NPDES inspections across the U.S. at facilities of varying types and sizes—from small construction sites, to the largest POTWs in the country, to complex industrial and manufacturing facilities. We are well-versed in both wastewater and stormwater collection, conveyance, and treatment systems, as well as their associated data management and assessment tools and technologies. Also, having conducted hundreds of MS4 inspections of both traditional and non-traditional programs throughout the U.S., our team is keenly aware of the current state of the MS4 landscape and dischargers’ ability to achieve the MEP standard.

National Aquatic Resources Survey

U.S. Environmental Protection Agency

Services: Ecological Services

Longear Sunfish in Texas, NRSA site TXRF-003

Continuously since 2012, PG has supported the U.S. EPA’s National Aquatic Resources Survey (NARS) in monitoring the health of our nation’s water resources. We provide broad-based technical support for three NAR’s assessments: the National Rivers and Streams Assessment (NRSA), the National Wetlands Condition Assessment (NWCA), and the National Coastal Condition Assessment (NCCA). Our work includes coordinating the complex logistics involved; mobilizing field teams to conduct sampling activities at hundreds of stream, wetland, and coastal locations across the U.S.; and coordinating with laboratories to ensure that samples are correctly processed.

MS4 Audits
