(a) By August 19, 2019, a community or nontransient noncommunity water supplier shall develop a comprehensive monitoring plan to assure that all sources, purchased interconnections and entry points are included in compliance monitoring at the entry points and within the distribution system. The plan must contain at least all of the following:
(1) A list of all sources, purchased interconnections, treatment plants and entry points permitted under this chapter. The availability of each source, treatment plant and entry point must be designated as either permanent or reserve. The availability of each purchased interconnection must be designated as either permanent or emergency. Permanent, reserve and emergency availability categories are as follows:
(i) Permanent—A source, treatment plant, entry point or purchased interconnection permitted under this chapter that is used on a regular basis. Permanent facilities must be included in compliance monitoring. Permanent entry points receiving water from a reserve source must be monitored in accordance with § 109.301(15) (relating to general monitoring requirements).
(ii) Reserve—A source, treatment plant or entry point permitted under this chapter which is not used on a regular basis, but remains on standby to augment or supplement permanent sources, treatment plants or entry points. A reserve source, treatment plant or entry points may not be used without prior written approval from the Department under § 109.703(d) (relating to facilities operation).
(iii) Emergency—A purchased interconnection permitted under this chapter which is used during temporary emergency situations.
(2) A schematic of all sources and associated treatment plants and entry points, purchased interconnections and the relative locations of the points of entry into the distribution system.
(3) For each entry point, a description of normal operating conditions, including whether the entry point provides water continuously, whether each source contributing to the entry point provides water continuously and whether sources are alternated or blended. For alternated sources, include the operation schedule for each source. For blended sources, include a description of the range of blending ratios.
(4) A description of how all permanent sources and permanent entry points are included in compliance monitoring.
(b) The plan must include the sample siting plans and monitoring plans required under other sections of this chapter, including the total coliform sample siting plan required under § 109.701(a)(5) (relating to reporting and recordkeeping), the monitoring plan for disinfectants, DBPs and DBP precursors required under § 109.701(g), the lead and copper sample site location plan required under § 109.1107(a)(1) (relating to system management responsibilities) and the source water sampling plan required under § 109.1202(h) (relating to monitoring requirements).
(c) The water supplier shall review and update the plan at least annually and as necessary to reflect changes to facilities or operations. The date of each update must be recorded on the plan.
