You must provide public notice to persons served as soon as practical but within 30 days after you learn of the violation [40 CFR 141.203(b)]. You must issue a repeat notice every three months for as long as the violation persists. Your primacy agency may have more stringent requirements for treatment technique violations. Check with your agency to make sure you meet all requirements. If this notice is for failing to address a fecal indicator-positive source sample, a Tier 1 notice for detecting a fecal indicator in the source water should have already been issued. Consider providing the history of the situation in this notice (i.e., what events lead to requiring corrective action) to avoid confusing the public when this second notice is issued. Community systems must use one of the following methods [40 CFR 141.203(c)]: Hand or direct delivery Mail, as a separate notice or included with the bill Noncommunity systems must use one of the following methods [40 CFR 141.203(c)]: Posting in conspicuous locations Hand delivery Mail In additional both community and noncommunity systems must use another method reasonably calculated to reach others if they would not be reached by the first method [40 CFR 141.203(c)]. Such methods could include newspapers, email, or delivery to community organizations. If you mail, post, or hand deliver, print your notice on your system's letterhead if available. The notice on the reverse is appropriate for mailing, posting, or hand delivery. If you modify this notice, you must still include all required PN elements from 40 CFR 141.205(a) and leave the mandatory language unchanged (see below). Mandatory Language Mandatory language on health effects (from Appendix B to Subpart Q) must be included as written (with blanks filled in) and is presented in this notice in italics and with an asterisk on either end. You must also include standard language to encourage the distribution of the public notice to all persons served, where applicable [40 CFR 141.205(d)]. This language is also presented in this notice in italics and with an asterisk on either end. Corrective Action In your notice, describe corrective actions you are taking. Listed below are some steps commonly taken by water systems with Ground Water Rule treatment technique violations. Depending on the corrective action you are taking, you can use one or more of the following statements, if appropriate, or develop your own text: x Although we did not meet our deadline, we are now in consultation with the state to develop a corrective action plan. x The [source of contamination/significant deficiency] has been identified and addressed. x We have implemented a short-term plan to address the immediate issue while we pursue the long-term solution. Repeat Notices For repeat notices, you should state how long the violation has been ongoing and remind consumers of when you sent out any previous notices. If you are making progress with correcting the significant deficiency or addressing the fecal indicator-positive source sample, describe it. Alternatively, if funding or other issues are delaying corrective action, let consumers know. After Issuing the Notice Send a copy to EPA Region 8 Drinking Water Unit (8WP-SDA), Attn: GWR Manager, 1595 Wynkoop Street, Denver, CO 80202 or email a copy of the PN and the certification to R8DWU@epa.gov. Make sure to send your primacy agency a copy of each type of notice and a certification that you have met all public notification requirements within ten days after issuing the notice [40 CFR 141.31(d)]. GWR Failure to Take Corrective Action Within Required Time Frame Public Notice IMPORTANT INFORMATION ABOUT YOUR DRINKING WATER (PWS Name) Failed to Correct a Significant Deficiency Within Required Time Frame.

S. Environmental Protection Agency (EPA) following a sanitary survey of the Green Creek Inn & RV water system on July 8, 2021. Please note each significant deficiency listed at the beginning of the report. To avoid receiving a violation, you must correct each identified significant deficiency and submit documentation of the corrective action to the EPA within 6 months from receipt of this letter and sanitary survey report. If you will be unable to meet this standard corrective action timeframe, you must contact the EPA with a written justification and proposed completion schedule as soon as possible. Each significant deficiency for this water system is listed below: SIGNIFICANT DEFICIENCIES Significant deficiencies for drinking water systems are defined as defects in the design, operation, or maintenance, or a failure or malfunction of the sources, treatment, storage, or distribution system that the EPA determines to be causing, or to have the potential for causing, the introduction of contamination into the water delivered to consumers. SIGNIFICANT DEFICIENCIES 1) Gravity Tank ID: ST01 - Cistern Storage tank not cleaned and inspected within the last 10 years. The tank must be cleaned and inspected. Please see the enclosed Finished Water Storage Tank Inspection/Cleaning Checklist for a list of items that must be evaluated during the inspection. Tanks need to be periodically cleaned and inspected to prevent the growth of potentially harmful pathogens in the accumulated sediments and to address construction issues before they require major repairs. Inspections and cleaning may be done by a third-party professional or appropriately trained in-house staff. Please be aware that some tanks may be considered as confined spaces or hazardous environments; personnel working in or near the tanks should have all OSHA-required training, and proper safety equipment and procedures should be used at all times. After inspection and cleaning the tank must be disinfected according to AWWA standards (C652-92: Disinfection of Water Storage Facilities). In order to correct this significant deficiency, you must provide EPA with the following documentation: A completed copy of the Finished Water Storage Tank Inspection/Cleaning Checklist. A copy of inspection results and labeled photographs. The date that any corrective actions needed to address deficiencies with the tank components will be completed. EPA will review the inspection report and may require additional corrective actions. 2) Gravity Tank ID: ST01 - Cistern Unknown integrity of storage tank access hatch gasket (see photo #11). The sanitary surveyor was unable to evaluate the tank access hatch, and the water system was not able to produce documentation of the condition of these components. Each item that could not be inspected during the sanitary survey must be inspected and the structure/condition must be compared to the enclosed Tech Tips for Finished Water Storage Facilities to determine if corrective action is needed. Tank inspectors can be third-party professionals or appropriately trained in-house staff. In order to correct this significant deficiency you must provide the EPA with the following documentation: A completed copy of the Unknown Integrity Checklist. A copy of the inspection report. The inspection report must describe the condition of each specified tank component and include photographs. The date that any corrective actions needed to address deficiencies with the tank components will be completed. EPA will review the inspection report and may require additional corrective actions. 3) Gravity Tank ID: ST01 - Cistern Hatch on Finished Water Storage Tank is not elevated to the required height* (see photo #11). The tank hatch must be elevated a minimum of 24 inches above the ground surface. 4) Gravity Tank ID: ST01 - Cistern Hatch on Finished Water Storage Tank does not have a shoe box lid* (see photos #11 and 13). The tank hatch must be fitted with a solid watertight cover which extends down around the frame at least two inches. 2 5) Gravity Tank ID: ST01 - Cistern Air vent screening on finished water storage tank improvement needed* (see photo #14). The vent must be fitted with non-corrodible #24-mesh screen to prevent contamination (including contamination carried by insects, rodents, and birds) from entering the water system. The screen should preferably be installed within the vent at a location least susceptible to vandalism. Correction of this deficiency will require a permit to construct from the WYDEQ and will require an evaluation by an engineering firm to ensure that no damage will occur to the existing water tank as a result of the modifications to address the significant deficiencies. Within 6 months from receipt of this letter, you must do the following: Prior to making physical modifications to your water system, a permit issued by the Wyoming Department of Environmental Quality (WY DEQ) may be required. Contact the respective WY DEQ District Engineer for your area to determine if a permit is needed before making corrections for significant deficiencies followed by an asterisk (*). The email and phone number for the DEQ District Engineer may be found on Page 2 of your Sanitary Survey Report. Correct each significant deficiency. Provide a completed Significant Deficiency Correction Notice listing each individual deficiency and the date of correction. If a WY DEQ permit was required to make any of the significant deficiency corrections, please include the permit number on your completed Correction Notice form. Provide labeled photos of each correction. If you will be unable to meet the 6-month standard corrective action timeframe, you must contact the EPA as soon as possible with a written justification and proposed completion schedule to receive a time extension. Your time extension request must include: - Your public water system name and number; - Description of why you will be unable to meet the 6-month timeframe; - Description of the corrective action(s) to be taken to address each significant deficiency; - A schedule including specific proposed dates for completing each corrective action, which may include short-term interim steps and long-term completion dates. The Significant Deficiency Correction Notice is enclosed and can also be found at the following website: http://www.epa.gov/region8-waterops/reporting-forms-and-instructions-reporting-forms and by selecting the Sanitary Survey link.
