Does a signed STIP affect a PRPs liability?
Signing a STIP does not increase a PRPs liability. A PRP is responsible for the cleanup regardless of whether the STIP is signed. By signing the STIP, the PRP expresses its desire to cooperate with DEC to clean up the spill. If the PRP is the discharger and DEC determines that enforcement is necessary, cooperation of the PRP is one of the significant issues considered by DEC when deciding on potential fines and/or penalties.
