In no case shall such a chemical liquid be disposed of in any floor drain, toilet, sink, sanitary sewer, storm drain, surface water body or on the ground.

(b) Monitoring Requirements

(1) Parameter Monitoring

(A) Each permittee must monitor the wastewater for the parameters specified in Tables 5-2a or 5-2b of this section per category of wastewater (e.g.

boiler blowdown or noncontact cooling water) at the frequency specified in Table 5-3 of this section in accordance with the methods specified in 40 CFR Part 136 to determine whether such discharge complies with the effluent limits and other conditions of this general permit.

DEEP-WPED-GP-012 Page 22 of 66 Rev. 05/03/18

(B) In addition, each permittee must monitor the wastewater at the frequency shown in Table 5-3 for any parameters specified in Table 5-1 of this section that are known or suspected to be present in the discharge.

(A) building maintenance wastewaters,

(B) fire suppression testing wastewaters,

(C) swimming pool wastewaters,

(D) discharges comprised of sources of groundwater and stormwater which enter private or public utility equipment manholes and/or vaults which are conveyed to a POTW by combined storm and sanitary sewers, and
