States with primary PWSS enforcement authority are authorized to grant variances and exemptions from National Primary Drinking Water Regulations due to particular situations with specific public water systems providing these variances and exemptions meet the requirements of SDWA, Sections 1415 and 1416, and are protective of public health.

B. Why is a review of the variances and exemption necessary?

Colorado is authorized to grant variances and exemptions to drinking water systems in accordance with the SDWA. The SDWA requires that EPA periodically review State issued variances and exemptions to determine compliance with the Statute. 42 U.S.C. 300g-4(e)(8); 42 U.S.C. 300g-5(d).
