Electronic Documents Submittal

In response to the Governor's request to limit contact and the move toward staff working remotely for the near future, the WDEQ Water Quality Division (WQD) has made electronic document submittal available. This includes permit applications, response to comments, reports, and other communications. Forms have been set up for individual WQD Sections (Watershed, WYPDES, Groundwater, Water/Wastewater), and a form is also available for general WQD submittals. Please choose the appropriate form from the list of links below to upload your documents. If submitted electronically, no hardcopy is required to be submitted unless you are contacted by a WQD Section Manager with a request to submit the hard copy. Please note that the Water Quality Division is unable to accept comments on documents in public notice via these forms. Please refer to the public notice for instructions on how to submit comments.

This page contains a downloadable QA/QC manual with important information on practicing correct methods, procedures and techniques. Adhering to these practices helps ensure environmental data quality and quality control. 


This page contains a downloadable version of the Watershed Protection Program Quality Assurance Project Plan (QAPP).

This document contains important information that establishes the degree of state defined use support for all waters of the state. Included in this document are explanations of a variety of project requirements, procedures, and instructions. 


This page contains current and previous years’ Quality Assurance/Quality Control Annual Reports.

These documents contain information on activities which were conducted for Quality Assurance/Quality Control during the listed year.

SAP Guidance

This page contains a downloadable version of the Watershed Protection Program Sampling and Analysis Plan (SAP) Guidance.

This document contains information on what must be included in an SAP and explanations of a variety of requirements, procedures, and instructions. 

This page contains information and resources about Quality Assurance/Quality Control under the Watershed Protection Program – including quality assurance project plans and other water quality assessment resources.

Each year, federal, state, private and public groups or agencies, industry, academic researchers and interested citizen organizations spend increasing amounts of time and money on water quality monitoring, data analyses and interpretation.

In order for the information gathered to be useful to other interested parties and to be used for an accurate, cost-effective and efficient assessment of water quality, all monitoring data must come from comparable project design, methods (including QA/QC), analyses and interpretation.

Collaboration among water quality monitoring programs and organizations is possible if there is a technical and administrative framework to promote data comparability and to assure data of known quality. In addition, environmental issues and related data operations are becoming increasingly complex.

Existing and anticipated environmental decision-making objectives drive the need to establish a systematic process and structure. Establishing these characteristics will ensure the data quality and consistency that decision-makers must have if they are to have confidence in the data that supports their decisions. 

Environmental data include any measurements or information that help describe the following:

  • Environmental processes, location or conditions
  • Ecological or health effects and consequences
  • The performance of environmental technology and/or
  • Information collected directly from measurements 

Environmental data quality assurance and quality control are achieved by adhering to the methods, procedures and techniques in this manual.
