Treatment Works Approval Permit Application Deficiencies

Below are some common permit application deficiencies:

Administrative Deficiencies

• The applicant listed on the TWA-1 Form is incorrect. The applicant should be the entity that will eventually own and operate the proposed treatment works.

• Signatures on the TWA-1, WQM-003, and WQM-006 series forms are older than 1 year and/or are not original.

• The application fee is not included with the application or is calculated incorrectly.

• Notifications to the Local Planning Board and Environmental Commission are not included (certified mail - return receipt requested).

• Engineering documents are not signed, sealed, and designated as final.

Technical Deficiencies

• Gravity sewer lines are designed below minimum slope requirements or are oversized to circumvent the need for a pump station and force main.

• The Engineer's Report (Form WQM-006) and the final construction plans are inconsistent.

• The site plan is incomplete (for example, plans do not show existing sanitary sewer lines, water mains, storm sewers, stream crossings, etc.).

• The design flow calculation is inconsistent with Department requirements and/or greater than the amount of flow approved by the owner of the receiving wastewater treatment facility.

• The engineering design deviates from the Department's requirements and adequate justification is not provided.
