OF ENVIRONMENTAL CONSERVATION RECEIVED ANCHORAGE DISTRICT OFFICE 3601 C STREET, SUITE 322 APR 2 6 19~1 ANCHORAGE, AK 99577 Mr. Tobben Spurkland, P.E. 6751 W. Dimond Anchorage, AK 99502-3904 Municipality of Anchorage Dept. Health & Human Services Re: WALTER J. HICKEL, GOVERNOR 563-6775 April 24, 1991 Certificate to Operate, Buckner Porter S/D, Lot 3 & Your Letter, Same Subject dtd March 1, 1991 Dear Mr. Spurkland: This is in response to your submittal, received in this office on March 1, 1991, in which you requested certification of the Class C public water system for the tri-plex located on the referenced lot. I have completed my review of the submitted information and this office's file on this project. The package has been discussed with the District Engineer and the following comments are offered. Subject source well has probably been in service since 1967 per the data you submitted. As such, the separation distance limits are as stated in your letter. In the event of future modification, alteration, or major repair, upgrade to meet current distances will probably be required or be waived (via a formal waiver request). The Department takes exception to the amount of storage capacity provided (you did not list any). The fifth edition of "Community Water Systems Source Book" cites a need for eight gallons per minute per residence for twenty minutes to meet instantaneous demand requirements. In this case a total of 480 gallons of water is required. The well produces 120 gallons in 20 minutes leaving a difference of 360 gallons which should be in usable storage. As there are no complaints in the Department files concerning the amount of water, the Certificate to Operate can be approved based upon historical sufficiency. Based on the information provided by you and the data certified by ~7our stamp, "Approval to Operate" can be granted. Although the well does not deliver the "book" volumes, your testimony verifies the ability of the source well to provide water to the users of Public Water System Id # 217055 (PWSlD# 217055); a Class C public water system. Any future expansion of the water system will require plan review in accordance with 18 Alaska Administrative Code 80.400. In all likelihood expanded storage capacity would be required to meet instantaneous demand. Please advise your clients of the regulation requirements for plan review for future alterations of the public water system. In accordance with 18 Administrative Code (A/kC) 80.900 this system is a Class C Public Water System. It has been assigned a Public Water System Identification Number (PWSID#) of 217047. Bacterial and nitrate sample analyses were within acceptable limits set in 18 AAC 80.050 as reported by Chemical & Geological Labs of Alaska. Enclosed is the current Certificate to Operate. Approval to operate is based on your professional recommendation and certified as-built drawings. This approval does not imply the granting of any additional authorizations nor obligate any state, federal, or local regulatory body to grant re,quired authorizations. Thank you for your cooperation with this Department. If you have any questions, please do not hesitate to contact Keven Kleweno. Sincerely, Karnowski Environmental Engineer enclosures cc: John Smith, DHHS w/o enc.
