CHEMICAL DISCLOSURE LIST
Colorado Revised Statutes(C.R.S.)34-60-132 requires oil and gas operators in Colorado to disclose the chemicals used in
downhole operations to certain persons and entities near their 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 is 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.Pursuant to C.R.S.34-60-132,Operators must provide the
chemical disclosure list to the interested parties defined in the law within 30 days after receipt of the chemical disclosure
list from the ECMC.
