MTBE monitoring will begin with the next compliance period for VOC's in accordance with the system's VOC testing schedule.
b. The analytical method utilized to test for methyl tertiary-butyl ether shall be EPA method 524.2. Only samples analyzed utilizing testing method 524.2 shall be accepted by the Department for determining compliance with 10-144 CMR 231 Section 7(G)(5).
D.Reporting, Public Notification and Record Keeping
1.Reporting requirements
a. Title 40 C.F.R. Section 141.31, published July 2014, is hereby incorporated herein by this reference.
b.

The reporting requirements shall be the same as that set for Volatile Organic Contaminants.
2.Reporting MTBE
a. The owner or operator of a public water system shall complete public notification for any failure to monitor or exceedance of the MCL for methyl tertiary-butyl ether. Public notification shall be completed with the same form, manner, and frequency as required by the Public Notification Rule for Volatile Organic Contaminants at 40 C.F.R. 141, Subpart Q. The mandatory health effect language as specified at 10-144 CMR 231 Section 7-D(2)(b) for methyl tertiary-butyl ether is to be placed in the public notification for any exceedance of the methyl tertiary-butyl ether MCL.
b.Mandatory health effect language for methyl tertiary-butyl ether

The State of Maine has set an enforceable drinking water standard (MCL) for methyl tertiary-butyl ether known as "MTBE." MTBE generally contaminates drinking water from leaking underground fuel tanks and accidental spills. This chemical has been shown to have adverse effects on laboratory animals after long term exposure to high levels. Chemicals which cause adverse effects in laboratory animals may also cause adverse effects in humans who are exposed at lower levels over long periods of time. The Department has set an enforceable drinking water standard for MTBE of 35 parts per billion to reduce the risk of adverse effects which have been observed in animals. Drinking water which meets this standard is associated with little to no risk and should be considered safe for human consumption.

3.Record maintenance
a. Title 40 C.F.R. Section 141.33, published July 2014, is hereby incorporated herein by this reference.
b. Any owner or operator of a public water system shall retain on its premises, or a convenient location near its premises, the records of analyses for methyl tertiary-butyl ether in the same form, manner, and frequency as that required for the Volatile Organic Contaminants at 40 C.F.R. 141.33 and as incorporated by reference in these rules at 10-144 CMR 231 Section 7(D)(3)(a) above.
