EPA and WSDOE Compliance Requirements for Construction Site Wastewater

Category:

If you’re a construction manager, your construction site must adhere to strict compliance requirements for wastewater management. Your site produces contaminated water that cannot return to surface waters around Washington. 

Instead, you must filter contaminants from the water that could harm human and animal health, ensuring adherence to the required construction compliance standards. The Environmental Protection Agency (EPA) and the Washington State Department of Ecology (WSDOE) have enacted clean water requirements for construction sites. 

Read on to learn the construction wastewater compliance requirements your site must adhere to. Then contact our team at Washington Stormwater to learn about our essential wastewater solutions. 

EPA Construction Wastewater Requirements

EPA construction wastewater regulations apply to all construction sites subject to NPDES permit requirements. This generally includes all sites with at least one acre of land disturbance. 

The EPA requires construction site operators to manage dewatering activities throughout their construction processes. They must also implement measures to prevent discharges of pollutants and maintain buffers around surface waters. 

Construction sites must use the best practicable technology currently available to enact wastewater treatments and prevent pollutants. Specifically, construction operators must: 

  • Minimize discharge of contaminants from wash waters on the construction site
  • Minimize the exposure of construction materials to precipitation and stormwater
  • Minimize discharge of pollutants from chemical spills and wastewater facilities
  • Minimize runoff from storm sewer systems

Additionally, the following types of discharges are prohibited: 

  • Fuels and oils
  • Wastewater from concrete washout
  • Wastewater from paint, stucco, form release oils, and other construction material washout
  • Soaps used in equipment washing 

You can learn more about these regulations by reading the Construction and Development Effluent Guidelines and Standards 40 CFR Part 450.

WSDOE Construction Wastewater Requirements

The WSDOE requires construction sites to adhere to the Construction Stormwater General Permit requirements. The requirements in this construction permit include:
