maintaining the new technology and compare these with thoseestimated in the engineering report, complete a reassessment of theexpected life of major components of the new technology, includethe engineer’s conclusion as to whether or not this technology waseffective for this public water system and include the engineer’srecommendation (with any reservations) as to whether or not thistechnology should be widely approved for similar application;g. If the public water system has maximum contaminant levelviolations, action level violations, treatment technique violations, orlow pressure violations at the frequency noted above in items a. andb., that, in the department’s opinion, could be the result of use of thenew technology, the department shall issue a preliminary intent todeclare the new technology ineffective for this public water system.The public water system shall then submit the engineeringevaluation within the time frame noted above in item f.;h. The department shall review the engineering evaluation andconduct other investigations as it deems necessary including, butnot limited to, investigations by department employees orcontractors, invitations to submit analysis from the vendor,manufacturer, and original project engineer (if different from theevaluation engineer). Within six months of submittal of theengineering evaluation by the public water system, the departmentshall make a formal determination of whether or not the newtechnology is ineffective for this public water system; andi. If the department formally determines the new technology isineffective for this public water system, the public water systemshall:1. Within 180 calendar days, submit engineering plans andspecifications prepared by a professional engineer registered inMissouri and a completed construction permit application to thedepartment for replacing the new technology with the standardtechnology identified in the original engineering report;2. Within 30 calendar days of receipt of any request from thedepartment for additional information or changes in theengineering plans and specifications, the public water systemshall submit these modifications to the department;3. Within 180 calendar days of the department’s approval toconstruct, the public water system shall construct the newfacilities; and4. Within 21 calendar days of completion of construction, thepublic water system shall submit to the department certificationby the professional engineer stating that the project has beensubstantially completed in accordance with the approved plansand specifications.Aug. 29, 2003Page 8
1.1.7.4. Performance Period.The length of the performance period shall be the lesser of 60 months orthe expected life of the major components of the new technology. The lifeof the contract shall be the performance period plus 12 months, whichincludes six months for the engineering analysis and six months for thedepartment’s final determination of effectiveness.1.1.7.5. (no title)Initially, the department will approve only one project for a particular newtechnology statewide. After the department completes review of the oneyear engineering evaluation of this first project, the department mayapprove an additional nine projects for a particular new technologystatewide. If any project is formally declared to be ineffective, allapprovals shall cease until the department reassesses the new technologyand determines if the failure was site specific or more general.1.1.7.6. (no title)After the completion of ten successful projects for a particular newtechnology and department review of all engineering evaluations, thedepartment may promulgate design regulations allowing the newtechnology to become standard technology or may allow additionalprojects to gather more information if needed. Ultimately, the departmentwill either promulgate regulations making the new technology standardtechnology or will declare the new technology inappropriate for use inMissouri.1.1.8. Project Sites.The area and approximate geometry of the proposed site shall be identified andthe adequacy for adding additional facilities on the site, and for providingadequate security. To the extent practical, all new or expanded water systemsshall not be located on sites:a. That are subject to a significant risk from earthquakes, floods, fires,pollution or other disasters which could cause a breakdown of the publicwater system or a portion of the system, and, except for intake structures,are within the floodplain of a 100-year flood where appropriate recordsexist;b. That are in the proximity of residences, industries, and other establishments;andc. With any potential sources of pollution or other factors that may influencethe quality of the supply or interfere with effective operation of the waterworks system, such as sewage absorption systems, septic tanks, privies,cesspools, sinkholes, sanitary landfills, refuse and garbage dumps.1.2. Plans.Plans for water systems shall be no larger than standard size 24 inches by 36 inches.Aug. 29, 2003Page 9
