List of Tables SCHEDULE A: WASTE DISCHARGE LIMITS Outfall 001 – Permit Limits BOD5 or CBOD5 and TSS [Adjust summertime dates as needed] May 1 – October 31. [Choose one of the following] During this time period the permittee may not discharge to waters of the state. [or] During this time period the permittee must comply with the limits in the following table: Table A1: BOD5 or CBOD5 and TSS Limits
A. (delete this row if it does not apply) Class A recycled water must be oxidized, filtered and disinfected. Before disinfection, unless otherwise approved in writing by DEQ. (include highlighted language only for legacy permittees with facilities in which the filtration process comes after the disinfection process. Delete from all other permits.) turbidity may not exceed: 2 NTUs within a 24-hour period. 5 NTUs more than five percent of the time within a 24-hour period. 10 NTUs at any time. After disinfection, total coliform may not exceed: A median of 2.2 organisms per 100 mL based on daily sampling over the last 7 days that analyses have been completed. 23 organisms per 100 mL in any single sample. A recycled water may be used for: Class B, Class C, Class D, and nondisinfected uses. Irrigation for any agricultural or horticultural use. Landscape irrigation of playgrounds, school yards, residential landscapes, or other landscapes accessible to the public. Commercial car washing or fountains when the water is not intended for human consumption. supply source for non restricted recreational impoundments. Artificial groundwater recharge by surface infiltration methods or by subsurface injection in accordance with OAR Chapter 340, Division 44. This clause should not be included unless the application has specifically requested artificial groundwater recharge as a beneficial use. Artificial groundwater recharge requires a groundwater monitoring plan, working with WRD, and it may require a UIC permit. It is described in the Recycled Water IMD at B. (delete this row if it does not apply) Class B recycled water must be oxidized and disinfected. Total coliform may not exceed: A median of 2.2 organisms per 100 mL, based on the last 7 days that analyses have been completed. 23 total coliform organisms per 100 mL in any single sample. Class B recycled water may be used for: Class C, Class D, and nondisinfected uses. Stand-alone fire suppression systems in commercial and residential building, non-residential toilet or urinal flushing, or floor drain trap priming. Water supply source for restricted recreational impoundments.
discharges. It may also be modified so that WET testing coincides with monitoring for parameters that may be contributing to toxicity. When possible, conduct WET testing concurrent with testing for insert list of parameters such as chlorine, ammonia, metals, etc. that may contribute to toxicity and for which testing is already required. If a particular test shows toxicity at include if there is a ZID: the acute (ZID) or the chronic (RMZ) dilutions, the permittee must re-test and if necessary evaluate the cause of toxicity as described in , condition 12?. the results do or do not show toxicity at dilutions corresponding to the edge of the [modify as needed: ZID and the mixing zone]. The corresponding dilutions are as follows: ZID: XX Mixing zone: XX A template for providing WET test results is provided below. Chronic toxicity For chronic toxicity: 24-hr composite, specify location, such as: taken after dechlorination and before the effluent flume. Location should be the same as monitoring for parameters that may contribute to toxicity. The permittee must submit the results of WET tests using the template below, along with laboratory reports.

Recycled Water Monitoring Requirements The permittee must monitor recycled water for outfall (insert outfall no.) as listed below. The samples must be representative of the recycled water delivered for beneficial reuse at a location identified in the Recycled Water Use Plan.
