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 June 13, 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

The Data Quality Assurance Program oversees all sections in the Water Quality Division. The underlying goal is to ensure that all environmental data (e.g., field-collected data, scientific literature) aligns with standard scientific methods, state statutes, and federal regulations for defensible decision-making. These objectives are accomplished by establishing QA/QC procedures, developing guidance and policy, and providing training and audits to ensure data credibility and compliance with state and/or federal requirements.
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:
Environmental data quality assurance and quality control are achieved by adhering to established methods, procedures, and techniques.
