Regulated Substances

The Wellhead Protection Ordinance defines regulated substances as: those substances listed in Section 22.261 herein when storage or use at a facility at any time of the year meets or exceeds those thresholds specified in Section 22.262. A Facility Operator may, at their choice, calculate the quantity of Regulated Substances stored or used on site as follows:

(a) Maximum Amount at Any One Time.

The Facility Operator may report the quantity of Regulated Substances stored or otherwise used on site as the maximum amount found on site at any one time during the course of a year. Where there are seasonal fluctuations in Regulated Substance use, the amount should be based on storage or use of Regulated Substances during peak times of the year; or

(b) Monthly Daily Average.

The Facility Operator may calculate the daily average of Regulated Substance storage or use on site over the course of a month. The Facility Operator must calculate this average using the anticipated quantity of Regulated Substances storage or use during peak months at the facility.
