(A) Measurements, tests, and analyses of the characteristics of wastewater to which reference is made in this chapter, shall be determined in accordance with 40 C.F.R. § 136 methods approved by the Manager and shall comply with state and federal law. Sampling locations, times, duration, and frequencies shall be determined on an individual basis subject to approval by the Manager. The discharger shall have the option to use, at his or her own expense, more complete approved sampling methods, locations, times, duration, and frequencies than specified by the Manager. Any additional results beyond those required are also to be reported to the control authority.
(B) Measurements, tests, and analyses of the characteristics of wastewater required by this chapter shall be performed by a qualified laboratory certified by the state. When the analyses are required of a discharger by the town, the discharger shall arrange for independent testing to be performed by a qualified laboratory certified by the state, and shall furnish copies of the results of the tests to the Manager. This independent testing shall be at the expense of the discharger.
(C) Monitoring of wastewater characteristics necessary for determining compliance with applicable pretreatment standards shall be conducted on the basis of the schedule below, unless more frequent monitoring is required by authority other than this chapter, or if the Manager determines that the characteristics of the specific discharge warrant more frequent monitoring.
Average Actual Discharge | Monitoring Frequency |
Less than 100,000 gallons per day | Semiannually |
100,000 - 999,999 gallons per day | Quarterly |
More than 999,999 gallons per day | Monthly |
(D) Monitoring of wastewater characteristics for any purpose other than determining compliance with pretreatment standards shall be conducted on a frequency deemed necessary by the Manager.
(E) Upon demonstration by any person that the characteristics of the wastewater discharge by that person are consistent, the Manager may reduce the monitoring frequency as may be required by authority other than this chapter. In no case shall the frequency of monitoring be less than semiannual for determining compliance with pretreatment standards.
(F) In determining the discharge characteristics, factors such as continuous, batch, or seasonal operation, as well as the information requirements of other provisions in this chapter, shall be considered by the Manager. The Manager may obtain wastewater samples as required to verify the consistency of discharge characteristics.
(G) Fees for any given measurement, test, or analysis of wastewater required by this chapter and performed by the town shall be the same for all classes of dischargers, regardless of the quantity or quality of the discharge, and shall reflect only direct cost. Costs of analyses by an independent laboratory at the option of the discharger shall be borne directly by the discharger.
