Location Chemical Disclosures

Colorado Revised Statutes (C.R.S.) 34-60-132 requires oil and gas operators in Colorado to disclose the chemicals used in downhole operations. Operators report chemical products used in downhole operations to the ECMC on a location by location basis. Information provided by Chemical Manufacturers and the oil and gas operator are aggregated by the ECMC into a chemical disclosure list for release to the public. Chemicals are reported on the list alphabetically, and include each chemical’s Chemical Abstracts Service Number (CAS Number) as assigned by the Chemical Abstracts Service.
