CO 80203 .f' .. <br />Phone (303) 866-3581 BOARD POLICY NO. 2001-2 <br />FAX (303) 866-3589 <br />http:r/ Revoked, Scroll for additional info Bill Owens <br />Governor <br />Renewal of Pump Installation Licenses Greg E. Walther <br />to Reflect Pump Categories Based on Production Rate Executive Director, DNR <br />Hal D. Simpson, P.E. <br />PROBLEM: Secretary <br />The National Ground Water Association (NGWA) has revised the examinations it administers to <br />persons seeking licensure or certification for the installation of pumping equipment. The NGWA has <br />adopted a general pump installation test for all applicants to be administered with an additional <br />examination based on pump production rate in gallons per minute (i.e. up to 100 gpm or greater than <br />100 gpm). Board Policy No. 2000-1 adopted by the Board of Examiners of Water Well Construction <br />and Pump Installation Contractors ("Board") on April 4, 2000 implemented a policy to reflect the <br />NWGA pump categories and adopted the categories in the Revised Water Well Construction Rules. <br />Since that time, the Board has issued new licenses pursuant to its policy and Rules that include the <br />NWGA categories. However, renewal of licenses issued prior to the NGWA changes and the Board's <br />subsequent policy and rules revision has continued to use the former pump categories defined in earlier <br />versions of the Water Well Construction Rules. To achieve consistency with the pump categories <br />adopted by the NGWA and the current Rules of the Board, it is necessary that renewed licenses reflect <br />the gallons per minute (gpm) rate of pumps authorized to be installed under the license. <br />DISCUSSION: <br />The Board has maintained consistency with the NGWA examinations in the issuance of licenses to <br />pump installation contractors. Licenses are currently issued in accordance with the types of licenses <br />stated in Rule 7.3 of the Water Well Construction Rules, but renewal of licenses issued prior to Board <br />Policy 2000-1 (April 4, 2000) has been pursuant to the previously used pump categories. With the <br />shift in emphasis to pump production (instead of motor horse -power) that the NGWA implemented in <br />its examination program and adopted in the Board's Rules, renewed licenses are no longer consistent <br />with the adopted pump categories defined by rate of production. The shift from using horse -power <br />(hp) to production rate (gpm) has resulted in both a potential overlap and void regarding pumps that <br />can be installed by those holding pump installation licenses issued according to the stated categories. <br />For instance, a contractor licensed to install pumping equipment up to 5 horse -power (corresponding to <br />100 gpm or less according to policy 2000-1) may find that he is asked to install a I hp pump in a <br />shallow alluvial well. The theoretical pumping rate for a 1 hp pump lifting water 30 feet is 125 gpm. <br />A contractor licensed to install pumping equipment that produces up to 100 gpm would not be <br />authorized to install the same pump. On the other hand, a contractor limited to the installation of <br />pumps up to 5 hp could not install a pump that would produce 100 gpm if the lift of water exceeds <br />about 200 feet, but a contractor licensed to install pumps with production rates up to 100 gpm would <br />be authorized to install a 10 hp pump to lift water 400 feet. To promote equity amongst the contractors <br />in the pump installation industry, the Board believes it is necessary to institute a policy that brings all <br />pump licenses under the current categories based on production rate. <br />BRAD AUSTIN, Denver; JANET BELLIS, Boulder, H.
