Regulations that Affect Environmental Services

Federal Regulations

Clean Water Act (Water Pollution Control Act of 1972 and Amendments)

The Clean Water Act (CWA) establishes the basic structure for regulating discharges of pollutants into the waters of the United States and regulating the water quality of surface waters.

National Pollutant Discharge Elimination System Permits

Regulate point and non-point source dischargers, effluent limits and required best management practices to remove pollutants from discharges. ttp://

City of Portland Stormwater Permit information

City of Portland Treatment Plant Permits

Total Maximum Daily Load

Regulations establish effluent discharge allowance for stream systems that are water quality limited. Virtually all of Portland's major streams are water quality limited for some pollutant parameter. Find TMDL information for the Willamette Basin.

City of Portland TMDL Implementation Plan

Safe Drinking Water Act (1974 and Amendments)

Mandates a variety of programs to protect drinking water supplies. While the Portland Water Bureau is the main regulated entity, Environmental Services does have to comply with a sub-set of the regulations through its UIC Program.

Underground Injection Control System Permit

These regulations set specific requirements for discharges through deep infiltration systems, such as City drainage sumps, to reduce pollution discharges to groundwater.

Portland Underground Injection Control (UIC) Program

Superfund (Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) of 1980 and amendments)

Regulates cleanup of uncontrolled hazardous waste sites to protect public health and the environment. The investigation area extends from the Columbia Slough to the Fremont Bridge.

Portland Harbor Superfund Program

Endangered Species Act (1973)

Regulates the conservation of threatened and endangered plants and animals and the habitats in which they are found. The law requires federal agencies to consult resources experts to ensure that actions they authorize, fund, or carry out are not likely to jeopardize the continued existence of any listed species or result in the destruction or adverse modification of designated critical habitat of such species.

State Regulations

Oregon is a delegated state for many of the federal and regulatory permit programs. In addition, the following state level regulations are compliance programs for Environmental Services:

State Land Use Law – Statewide Planning Goals (1973)

The 19 goals express the state's policies on land use and related topics, such as citizen involvement, housing, and natural resources. Oregon´s statewide goals are achieved through local comprehensive planning. State law requires each city and county to adopt a comprehensive plan and the zoning and land-division ordinances needed to put the plan into effect. Goals 1 (Citizen involvement), 5 (Natural areas), 7 (Natural hazards), 10 (Public Facilities) and 15 (Willamette Greenway) are the most related to BES programs.

SB 737

Concern about toxic pollutants in Oregon’s waterways and environment led to the passage of Senate Bill 737 in 2007 which directed Oregon DEQ to identify persistent pollutants and assess their presence in Oregon’s municipal wastewater treatment plants.
