Septic tank approval 


The Department will conduct one review per tank application to determine compliance with the applicable rules. After review, tank plans and installation manuals requiring correction will be returned to the manufacturer and engineer. All application materials returned for correction must be re-submitted to the Department within 60 days of notification. If there is a failure to correct all noted deficiencies and/or the information requested is not submitted within 60 days it will result in a new application fee assessment to continue the approval process.
