The Department of Environmental Quality has revised Water Quality Rules, Chapter 12, Design and Construction Standards for Public Water Supplies.
The revisions include the incorporation by reference of specific sections of the Recommended Standards for Water Works, 2018 Edition, in accordance with W.S. ? 16-3-103(h); new paragraphs that require public water supplies that propose acidization to submit plans that describe existing wells in the proposed area, mitigation plans, local geology, and placement and integrity of the annular seal and casing of the well so that the Water Quality Division may ensure the acidization activities do not negatively impact underground sources of drinking water that are in the vicinity of the proposed activities; the addition of requirements for treatment technologies, including ultraviolet and membrane technologies, that have become widely used since the chapter was originally promulgated in 1985; the correction of outdated references, formatting, numbering, and grammar errors; the removal of metric units that are redundant to English units; the removal of introductory statements that are redundant to passages that follow the removed statements; the alignment of requirements with the statutory authority of the Water Quality Division; the reorganization of sections to group passages with other similar passages; the reorganization of passages to clarify requirements; and the addition of a new section that identifies the information incorporated by reference, in accordance with W.S. ? 16-3-103(h).
The Environmental Quality Council adopted the revised rules at a public hearing held on May 16, 2023, in the Board of Equalization Meeting Room, Hathaway Building 1st Floor, 2300 Capitol Ave, Cheyenne, Wyoming. The final rule was filed with the Wyoming Secretary of State on July 26, 2023.
