Permit For those facilities electing to employ the TTO monitoring waiver, the discharger shall sign the following certification statement
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics

Facilities that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may so certify, and the requirement for TTO monitoring
may be waived The solvent management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General
Permit For those facilities electing to employ the TTO monitoring waiver, the discharger shall sign the following certification statement
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics
(TTO), I certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics into the stormwater or areas which are exposed to rainfall or
stormwater runoff has occurred since filing the last discharge monitoring report I further certify that this facility is implementing the all the provisions of the
