"Total Recoverable Metals" means that portion of a-water and suspended sediment sample measured by the total recoverable analytical procedure described in "Methods for Chemical Analysis of A'ater and Wastes, " U.S. Environmental Protection Agency, Mazch 1979 or its equivalent. 17. "Twenty four (24 hour composite" sample is a combination of at least eight (8) sample aliqquots of at least 100 milliliters, collected at equally spaced intervals during the operating hours of a facility over atwenty-four (24) hour period.. For volatile pollutants, aliquots must be combined in the laboratory immediately before analysrs. The composite must be flow proportional; either the time interval between each aliquot or the volume of each aliquot must be proportional to either the wastewater or effluent flow at the time of sampling or the total wastewater or effluent flow since the collection of the previous aliquot. Aliquots maybe collected manually or automatically. 18. "Twice Monthly" monitoring frequency means that two samples shall be collected each calendaz month on sepazate weeks with at least one full week between the two sample dates. Also, there shall be at least one full week between the second sample of a month and the fust sample of the following month. 19.

The history shall include a discussion on the cause of the. spills and a the preventanve measures designed to eliminate them from reoccumng; b. An update of the reporting system which will be used to notify, at a minimum, responsible facility management, the Division, the Environmental Protection Agency, downstream water users within 5 miles downstream of the factlity, and local health officials; c. A description of any changes in the preventative facilities (iacluding overall facility plot) which prevent, contain, or treat spills and unplanned dischazges; d. A current list which includes Use volumes or quantities of all materials used, processed, or stored at the facility which represent a potential spill threat to surface waters. The location of stored material shall be indicated on the facility plot submitted for item c; e. An implementation schedule for additional facilities which might be required in item c, but which are not yet operational; f. A cunent list of available outside contractors, agencies, or other sources which could be utilized in the event of a spIll in order to clean up its effects. If the facility is capable of handling spills in-house, this shall be documented in the plan; g. Provision for yeazly review and updating of the contingency plan, plus resubmission of the plan to the Division if conditions and/or procedures at the facrlity change the original plan. The foregoing provisions shall in no way render inapplicable those requirements imposed by the Federal Water Pollution Control Act, 33 II S.C. § 1321, regulations ppromulgated thereunder, the Colorado Water Quahty Control Act, and re lations promulgated thereunder.

Should additional materials exist on site which are not addressed in the SPCC Plan, addressing those matenals as per the above is required. I/ If there is no such material presrn[ a[ the site, this shall be indicated in writing and submitted to [he Division for review. 2/ If there is material presrn[ but the permittee feels [here is not a reasonable probability of a spill impacting waters of [tic State, this shall be documented in writing and submitted ro the Division for review.
