Important Additional Lab Service Information

6. All incoming raw materials testing that cannot be accomplished by the onsite lab shall be included as well. This testing may be found on the individual materials specifications.

5. The equavalent of a complete semi-annual compliance sampling event should be added annually to the above items for purposes of estimating project analysis for wastewater process improvement projects and special projects.

4. Sampling will need to occur when the new equipment is fully operational in the form of a baseline monitoring compliance sampling event for both system outfalls, the PWPP and the new WSWPP. This is separate from counting as a semi-annual sampling event.

1. The above chart shows estimated compliance sampling as noted in the current wastewater discharge permit Attachment 1.

2. The current permit, however, only runs through August 1, 2018. Therefore, sampling shown to occur after that date is subject to change.

3. Additional sampling occurs when DC Water comes in once annually to perform compliance sampling, in that split samples are collected and analyzed. The effect of the DC Water split sampling analysis is equavalent to an additional complete semi-annual sampling event for all outfalls.
