This bill expands Washington’s water quality tools by requiring the Department of Ecology to offer water quality trading programs to polluters (like cities and industries) that discharge to temperature-impaired waters and are out of compliance — allowing them to meet pollution limits through trades rather than only infrastructure upgrades. It also reinforces Ecology’s authority over the NPDES permit program and includes incentives for urban heat island mitigation.

  • Requires the Department of Ecology to offer a watershed-based water quality trading program to NPDES permittees that discharge to waters with a total maximum daily load (TMDL) for temperature and are not in compliance — this program allows them to meet pollution limits through market- or community-based trades instead of only hardware upgrades.
  • Directs the Department of Ecology to offer incentives when possible for permittee improvements in the built environment or actions that reduce the urban heat island effect, which can raise water temperatures.
  • Reaffirms the Department of Ecology’s authority to administer the National Pollutant Discharge Elimination System (NPDES) permit program, including authority to delegate certain animal feeding operation responsibilities to the Department of Agriculture under a formal agreement.
  • Sets deadlines for reissuing and updating municipal stormwater general permits in western and eastern Washington, with updated requirements (e.g., low-impact development, catch basin inspections) phased in no earlier than December 31, 2016 or local code update timelines.

Who is affected

  • Municipal stormwater permitteesMunicipalities in western and eastern Washington that operate stormwater systems and hold National Pollutant Discharge Elimination System (NPDES) permits — they will need to comply with updated permit requirements, including new standards for low-impact development and more frequent inspections.
  • Industrial and agricultural point source pollutersFacilities like factories, farms, and other businesses that discharge pollutants into waterways and hold NPDES permits — they may be offered participation in a water quality trading program to help meet pollution limits, especially if discharging to waters with temperature limits.
  • Local planning and development authoritiesLocal governments responsible for updating development codes and stormwater management plans — they must align local rules with state low-impact development standards by specified deadlines.
  • State agencies (Ecology and Agriculture)The Washington State Department of Ecology and Department of Agriculture — Ecology retains primary authority but may delegate certain animal feeding operation responsibilities to Agriculture under a formal agreement.

Pro/Con Analysis

Stronger case for benefits

Potential Benefits (5)
  • Creates a market- or community-based water quality trading program for temperature-impaired waters, offering a potentially more cost-effective and flexible alternative to hardware upgrades—reducing runoff temperatures and improving aquatic habitat, directly benefiting public fisheries, recreation, and drinking water quality.

    EnvironmentPeopleRef: Sec. 1(5)
  • Incentives for urban heat island mitigation (e.g., green roofs, reflective surfaces, tree canopy) reduce localized heating in cities, lowering energy demand, improving air quality, and reducing heat-related illness—especially beneficial in low-income urban neighborhoods with fewer green spaces.

    Public SafetyPeopleRef: Sec. 1(5)
  • Mandates increased catch basin inspections and illicit discharge detection, improving stormwater quality and reducing contamination of drinking water sources and salmon habitats—benefiting public health and ecosystem resilience statewide.

    Public SafetyPeopleRef: Sec. 1(1)(a)(viii), Sec. 1(3)(b)(ii), Sec. 1(4)(b)(ii)
  • Requires low-impact development standards in local codes, promoting smarter growth and reducing long-term infrastructure costs—though implementation is delayed, the policy aligns with existing state growth management goals and could reduce future flood and erosion damages.

    Local GovernmentLean peopleRef: Sec. 1(1)(a)(x)
  • Clarifies and reaffirms Ecology’s authority over NPDES permitting—including delegation to Agriculture for animal feeding operations—reducing regulatory ambiguity and potential jurisdictional gaps that could otherwise delay pollution control.

    Local GovernmentLean peopleRef: Sec. 1(1)
Potential Concerns (5)
  • Mandates that permittees (including municipalities and industrial facilities) comply with new water quality standards or participate in trading programs, potentially increasing compliance costs for small municipalities and businesses that lack resources to develop or purchase credits.

    Business & EmploymentRef: Sec. 1(5)
  • Delays implementation of key stormwater requirements (e.g., catch basin inspections, low-impact development) until December 31, 2016 or local code update timelines—delaying public health and environmental benefits while imposing future compliance burdens on local governments when they are already stretched.

    Local GovernmentRef: Sec. 1(3)(b)(ii) and Sec. 1(4)(b)(ii)
  • Authorizes Ecology to impose user charges as part of its permit program, which could translate into new fees for businesses and municipalities—potentially passed on to consumers or used to reduce other local taxes, but primarily benefiting state revenue and potentially large entities that can absorb or offset costs.

    Business & EmploymentLean industryRef: Sec. 1(1)(c)
  • Requires local governments to update development codes to incorporate low-impact development standards by deadlines tied to state permits—imposing unplanned regulatory and administrative costs on cities and counties, especially smaller jurisdictions without planning staff or legal resources.

    Local GovernmentLean industryRef: Sec. 1(1)(a)(x)
  • Water quality trading programs may reduce local control over pollution reduction strategies, potentially allowing localized hotspots if trades concentrate in certain areas—though the bill includes no explicit monitoring or equity safeguards to prevent this.

Who Is Most Affected

Municipal stormwater permitteesMixed Impact

Municipalities face new compliance costs and administrative burdens, especially smaller jurisdictions without planning resources—but benefit from flexible trading options and delayed implementation timelines that allow time to adapt.

Industrial and agricultural point source pollutersPositive Impact

Industrial and agricultural polluters gain a new compliance pathway (trading) that may be cheaper than infrastructure upgrades—especially beneficial for large facilities with capital and technical capacity to participate in markets; small farms may lack access to trading partners.

Local planning and development authoritiesMixed Impact

Local planning authorities must revise development codes to meet state standards, incurring costs—but benefit from alignment with state growth management goals and potential federal funding for low-impact development projects.

State agencies (Ecology and Agriculture)Positive Impact

Ecology retains primary authority and gains flexibility to delegate animal feeding operation oversight—strengthening its regulatory role but requiring interagency coordination. Agriculture gains delegated authority but only under Ecology’s supervision.

Urban residents in heat-vulnerable neighborhoodsPositive Impact

Low-income urban residents benefit from heat island mitigation (e.g., tree planting, cool roofs) that reduces energy costs and health risks—but may not directly benefit from trading programs unless local projects prioritize equity.
