Recent General Permit Authorizations

The DEQ Water Quality Division accepts comments on all permits authorized under a general permit for a period of 30 days, as provided for in W.S. 35-11-801(d).

Interested persons may mail or fax comments to the main Cheyenne office. The ‘Date’ column in the table below indicates the date the authorization was posted to the website. Comments must be received before 5:00 pm on the 30th day after the authorization was posted to the website. For example, comments for an authorization posted on 10/1/18 must be received by 5:00 p.m. on 10/31/18. DEQ does not accept emailed comments.

You may sort the table by posting date or search for the type of general permit, the county where the permit was issued, the permit number, or the name of the person or company to whom the permit was issued.

If you wish to review the general permit documents, please go to the web page for each permitting program:

Proposed Rules and Regulations

The Water Quality Division will present proposed revisions to Water Quality Rules Chapter 1, Wyoming Surface Water Quality Standards; and Chapter 2, Permit Regulations for Discharges to Wyoming Surface Waters to the Water and Waste Advisory Board at their December 12, 2024 meeting, starting at 9:00 a.m. The proposed revisions to Chapter 1 (1) fulfill the federal requirements at 40 CFR § 131.20, (2) restructure and align requirements with state law and federal law, regulations, and guidance; (3) revise designated uses and remove the designated use classification system; and (4) provide minor updates to specific water quality criteria. The proposed revisions to Chapter 2 (1) update references to the designated use classification system to reflect proposed revisions to Chapter 1; and (2) incorporate provisions related to fish toxicants, aquatic pesticides, and short-term sediment disturbance that Water Quality Division proposes to move from Chapter 1 to Chapter 2. More information is available at: http://deq.wyoming.gov/shwd/wwab/ under the “Upcoming Meeting” tab

TMDL

States are required to develop total maximum daily load (TMDL) pollutant levels for waterways that are not adequately meeting federal Clean Water Act water quality standards. 

What is a Total Maximum Daily Load (TMDL)?

TMDLs are a requirement of Section 303(d) of the Clean Water Act (CWA).  According to the CWA, each state must develop TMDLs for all the waters identified on their Section 303(d) list of impaired waters.   A TMDL is a calculation of the maximum amount of a pollutant that a waterbody can receive while still meeting water quality standards.  An overview of TMDLs is provided on EPA’s website. Simply, a TMDL is a plan to achieve water quality standards for impaired waterbodies.

In general, states are responsible for developing TMDLs and submitting them to EPA for approval. Even if third parties assist in the development of the TMDL or its supporting analysis, such TMDLs must still be submitted to EPA by the states.

Under the CWA, the EPA reviews and either approves or disapproves the TMDL. If EPA disapproves a state TMDL, EPA must develop a replacement TMDL.

The Process

The TMDL Program coordinates with several other DEQ programs including the Monitoring, Assessment, Permitting, and Nonpoint Source Programs to accomplish water quality restoration goals in Wyoming.   TMDLs are one step in the “water quality restoration pipeline”.

Listing

The process begins when a waterbody is placed on the 303(d) list due to an exceedance of one or more water quality standards.  Once an impaired water is placed on the 303(d) list, water quality restoration planning begins. 

Planning

The TMDL is the planning step in the process where sources of pollution to streams, rivers, and lakes within Wyoming are identified and it is determined by how much pollution those waters can sustain and still fully support beneficial uses.  

Implementation

TMDLs are not self-implementing.  Rather, TMDLs are implemented through existing regulatory and non-regulatory drivers.  Point sources of pollution are addressed through the Wyoming Pollution Discharge and Elimination System (WYPDES) permit program.  Federal regulations require that discharge permit limits be consistent with the assumptions and requirements of any available wasteload allocation in approved TMDLs (40 CFR 122.44(d)(1)(vii)(B)).  Non-point sources load reduction actions are implemented through a wide variety of programs at the state, local and federal level. These programs may be regulatory, non-regulatory or incentive-based (e.g., a cost-share program).  Wyoming works closely with conservation districts and watershed stakeholders through voluntary actions, often with support from Wyoming’s Nonpoint Source Program using Clean Water Act Section 319 and 205(j) grant funds for projects aimed at reducing the nonpoint source pollution.

Monitoring and Adaptive Management

Follow-up monitoring to examine water quality trends over time, and BMP effectiveness monitoring to evaluate the efficacy of implemented best management practices, are important components of the process.  Achieving the ultimate goal of meeting the applicable water quality standards often takes many years and follow-up monitoring data can both facilitate and inform adaptive management actions, and track progress over time.  Much of the follow-up monitoring in Wyoming is conducted by watershed stakeholders with technical support provided by WDEQ.
