1. (a) The WWTP design shall provide flexibility for operating within the expected range of wastewater characteristics and volumes.

2. (b) A pilot test that complies with Env-Wq 717.04 shall be conducted for a proposed treatment technology if:

   1. (1) Effluent permit limits are at or near the limits of the proposed treatment technology;

   2. (2) Anticipated wastewater characteristics:

      1. a. Are not typical of those commonly received by a WWTP due to low- or high-strength effluent, high strength sidestreams, or industrial waste contributions; and
      2. b. Have a recognized potential to adversely affect the performance of the proposed treatment process; or
   3. (3) Extreme weather or population fluctuations have a recognized potential to adversely affect the technology’s performance.
3. (c) The owner shall submit a basis of design report as described in Env-Wq 707.02 through Env-707.07 to the department for review and approval prior to final design.
