10 - Year Water Quality Roadmap

Excess nutrients can degrade the quality of our drinking water, impair recreational boating and fishing experiences, and harm fish and aquatic species. The EPA and the commission have directed Colorado to adopt nutrient criteria to protect our streams and lakes. In October 2017, we established a water quality roadmap that outlines our strategy for developing nutrient criteria and other water quality priorities over ten years from 2017 to 2027.

COG641000 - Water Treatment Plant Wastewater Discharge General Permit

The Water Quality Control Division has quarterly webinars for Colorado Discharge Permit System permittees. These webinars provide permittees with up-to-date information on division permitting activities that could affect permittees and their future permits. Sometimes, there are opportunities to provide feedback. The webinars are open to the public; anyone is welcome to attend.

COG641000 Water Treatment Plant Discharges Permit

The Water Quality Control Division is beginning a stakeholder effort to renew the COG641000 water treatment plant discharge permit. We will be hosting two meetings during this effort. All current permittees will be invited to participate in the stakeholder engagement process. Following the stakeholder feedback process, the division will release a draft COG641000 renewal permit that includes an additional opportunity to provide input via a public comment period. After the public comment period, the renewal permit will be issued, and the division will begin renewing and re-issuing all existing permit certifications.

COR400000 - General Construction Permit Renewal

The current construction stormwater discharge general permit expires on March 31, 2024, and the division expects to renew the permit effective April 1, 2024. The permit outlines necessary compliance with water quality standards via practice-based limitations and requirements. The renewed permit will include updates made to add clarity. 

Prior to renewal, all permittees who have not done so must claim their facilities in Colorado Environmental Online Service (CEOS), the division’s online application system; this can be done at any time.

Lead and Copper Rule Revisions (LCRR)

The EPA recently published the Lead and Copper Rule Revisions (LCRR) that include significant changes to the current Lead and Copper Rule. The goal of the LCRR is to better protect communities from lead exposure in drinking water. EPA has also announced its intention to further strengthen regulatory requirements through the Lead and Copper Rule Improvements (LCRI), which they plan to finalize in late 2024.

Minimum Required Course Content 2024 Update

The division has updated the minimum required course content for Colorado water and wastewater facility operators to reflect recent regulatory changes and clarify content for trainers. Anyone delivering Mandatory Regulatory Training (MRT) courses in Colorado must incorporate these changes into their MRT training to receive Colorado Certified Water Professionals (CCWP) MRT credit in 2024.

Reg. 64 – PFAS and Biosolids

In early 2022, the division plans to evaluate if any interim changes are needed to Regulation 64 and/or its implementing authorizations, policies, and practices to address potential risks associated with PFAS in biosolids.

Reg. 86 - Graywater control

On May 7, 2018, the Water Quality Control Commission held an informational hearing to gather feedback for a proposed rulemaking scope to update Regulation 86 - Graywater Control Regulation. The division initiated the stakeholder engagement process and placed the effort on hold due to competing obligations, limited resources, and the COVID-19 pandemic.

The division presented an update on the stakeholder engagement schedule with the Commission in May 2021 as part of the triennial review process. As a result of the meeting, the stakeholder engagement schedule for Regulation 86 was postponed until 2022.

Suncor in North Denver

Suncor Permit Renewal

Suncor has two permits that allow for the discharge of pollutants into Sand Creek, which are up for renewal in 2021, CO0001147 and COS000009. CO0001147 allows Suncor to discharge refinery process wastewater and remediated groundwater into Sand Creek. COS000009 allows Suncor to discharge stormwater off its site into Sand Creek. Before renewing these permits, the division must include requirements and identify pollutant limits that will protect Sand Creek and downstream waters to maintain their beneficial uses (such as recreation, fishing, agriculture, and drinking water). The division seeks community input on the requirements and pollutant limits needed to protect Sand Creek and downstream waters.

Waters of the United States (WOTUS)

The Clean Water Act gives EPA and the U.S. Department of the Army the authority to define "waters of the United States" in regulations, and the Armny issues 404 permits to protect waters of the United States from dredging and fill activities. 

The Supreme Court decision in Sackett v. EPA will result in fewer water quality protections for Colorado. The department will use policy to guide any enforcement actions on the discharge of unpermitted dredged and fill materials into state waters.

Water Quality Fee Setting Rule

The fees that support the division are set in statute, and federal funding has remained flat through the years making it difficult to achieve long-term fiscal sustainability and provide a higher level of customer service. The Water Quality Fee-Setting by Rule proposal removes clean water and drinking water fees from statute and instead directs the Water Quality Control Commission to set fees in regulation.

Industrial stormwater general permit for non-extractive industries

The Water Quality Control Division is renewing the general permit to discharge stormwater associated with non-extractive industrial activity and would like input from the public and regulated entities. In order to protect Colorado waters from pollutants in stormwater runoff, the division requires operators of certain industrial facilities to obtain permit coverage for actual or potential discharges of stormwater. This permit requires facilities to implement a stormwater management plan, implement specific stormwater control measures, also known as best management practices, perform inspections, and monitor pollutants in their discharge.

Reg. 22 - Site Location and Design Regulations for Domestic Wastewater Treatment Works

The division is hosting routing discussions on the last Monday of each month until May 2023 to determine the feasibility of future regulatory changes for construction flexibility and historical infrastructure that does not have documentation demonstrating site location and design approval.
