The provisions of Colorado Revised Statute Sections 25-8-202(1)(c) and (2), 25-8-205(1)(e), 25-8-501(1) and (2), and 25-8-509 C.R.S, provide the specific statutory authority for the Colorado Biosolids Regulations adopted by the Commission. The Commission has also adopted, in compliance with Colorado Revised Statute Section 24-4-203(4) C.R.S., the following Statement of Basis and Purpose.
BASIS AND PURPOSE
The Commission found it necessary to clarify, modify or update four parts of these regulations.
An option was added to section 64.15 D(1) and 64.15 G(2) that allows the Division to approve additional means to determine the depth to groundwater and depth of suitable soil. This allows more flexibility for the Division when a permittee is trying to determine these levels.
Under section 64.15 H(2), the language was expanded to allow the use of operation plans to allow more flexibility in determining the application rate for reclamation sites.
Under section 64.15H(5), the phosphorus values and references were updated to be consistent with other federal and state programs. This will make it easier for the permitted community to be in compliance.
Finally, the Commission found that re-wording section 64.16 A(1) clarified the number of tests that need to be performed on biosolids prior to beneficial use and which facilities need to test.
