Part I Page No. 11 Permit No.: CO-0045225 g. Provision for yearly review and updating of the contingency plan, plus resubmission of the plan to the Division if conditions and/or procedures at the facility change the original plan. The foregoing provisions shall in no way render inapplicable those requirements imposed by Federal Water Pollution Control Act, 33 U.S.C. § 1321, regulations promulgated thereunder, the Colorado Water Quality Control Act, and regulations promulgated thereunder. It is recommended that this plan be prepazed by a professional engineer registered in the State of Colorado. Nothing herein contained shall be cons[rued as allowing any discharge to waters of the State other than through the discharge points specifically authorized in this permit. Nothing herein contained shall be construed as excusing any liability the permittce might have, civil or criminal, for any spill. The submittal of a Spill Prevention Control and Countermeasure Plan (SPCC Plan) as required by 40 CFR Part 112 may satisfy all or part of this requirement. Should additional materials exist on site which are not addressed in the SPCC Plan, addressing those materials as per the above is required. j/ If there is no such material prcunl at the site, this shall be iMlated in writing and submitted m die Division for review. ~l If thcrc is material prcscnt but the permittee feels there is not a reasonable proWbiliry at s spill impacting wafers or the Snte, this shall be documemcd in writing aid submited m die Division for review. This documcnration shall include; 1) distartee to nearest surface waters, aM; 2) a detailed description of any swcWrc which prohibits the release of marerial onto the grourd ar irno a wnveytntce rynem. F. GENERAL REQUIItEMENTS 1. Representative Sampling Samples and measurements taken as required herein shall be representative of the volume and nature of the monitored discharge. All samples shall be taken at the monitoring points specified in this permit and, unless otherwise specified, before the effluent joins or is diluted by any other wastestream, body of water, or substance. Monitoring points shall not be changed without notification to and approval by the Division. 2. Ana vocal and SamQ ine Methods for MonitorinE The permittee shall install, calibrate, use and maintain monitoring methods and equipment, including biological and indicated pollutant monitoring methods. Analytical and sampling methods utilized by the discharger shall be approved methods as defined by Colorado Regulations for Effluent Limitations (5 CCR 1002-3, 10.1.5), and federal regulations (40 CFR 136) and any other applicable State or Federal regulations. The analytical method selected for a parameter shall be the one that can measure the lowest detected limit for that parameter unless the permit limitation or stream standard for those parameters is within the testing t-ange of another approved method. When requested in writing, the Water Quality Control Division may approve an alternative analytical procedure or any significant modification to an approved procedure. When the most sensitive analytical method which complies with this part, has a detection limit greater than or equal to the permit limit, the pertnittce shall report "less than (We detectable limit),' as appropriate. Such reports shall not be considered as violations of the permit limit. The present lowest method detection limits for specific parameters (which have limitations which are, in some cases, less than or equal to the detection limit) are as follows: Arsenic O.OI mg/f Benzene 0.001 mg/Q Total Residual Chlorine 0.05 mglQ Cadmium 0.0003 mg/P Chromium 0.01 mg/P Chromium, Hezavalent O.OI mg/I Copper 0.005 mg/Q Cyanide, Weak Acid Dissociable O.Of0 mg/Q
