WAIVER CHECKLIST

Use Waivers: (R309-600-16(3))

Use waivers may be obtained if the chemicals within the pesticide and VOC parameter group have not been used in zones one, two or three in the last five years. To qualify, you must:

Provide a list of chemicals used, disposed, stored, transported, and manufactured at each potential contamination source (PCS) within protection zones 1, 2 and 3 where the use of chemicals
within the VOC and/or pesticide parameter groups is likely.

Submit a dated statement, signed by the system’s designated person, that none of the VOCs and/or pesticide within these respective parameter groups have been used, disposed, stored,
transported, or manufactured within zones one, two and three in the last five years.

Susceptibility Waivers: (R309-600-16(4))

Susceptibility Waivers tolerate the use, disposal, storage, transport, and manufacturing of chemicals within zones one, two and three if the PWS can demonstrate that the source is not
susceptible to contamination from them. To qualify, you must:

Submit the monitoring results of at least one sample from the VOC and/or pesticide parameter group taken in the last six years. A non-detect result is required.

Submitted a dated statement, signed by the systems designated person, that the PWS is confident that a susceptibility waiver for pesticides and or VOCs will not threaten public health.

Verify that the source is developed in a protected aquifer (R309-600-6(1)v). To do this, you must:

Provide evidence that there is a naturally protective layer of clay, at least 30 ft thick, above the aquifer
Provide evidence that the well is grouted to 100 feet, and that the grout extends through the protective clay layer. You may apply for an exception to this if the well was drilled
using a cable tool.
Provide evidence that the clay layer is laterally continuous throughout protection zone 2.

Have a public education program, described in the DWSP management plan, that addresses proper use and disposal of pesticides and VOCs

Use and susceptibility waivers must be updated each time your Drinking Water Source Protection Plans are updated or they will lapse.

Reliably and Consistently Waivers: Rachael Cassady (536-4467) can discuss these criteria with you. The compliance section grants these waivers based on monitoring results.
