No Exposure Certification:

  • If all industrial activity at your facility takes place inside and away from stormwater exposure, you may be eligible for a "no exposure" exemption from the stormwater permit and its associated requirements. Grapewell's engineering team will certify that your facility qualifies and then prepare and submit all necessary documentation.
