3 5. The Owner needing the Certificate of I&I Compliance replaces or relines the Service Lateral upon the occurrence of one of the events in subsections 3A or B. Section 4. Application and Fees. The property owner shall complete an application for a Certificate of I&I Compliance in the form prescribed by [municipality] prior to the occurrence of any of the events in Section 3A and upon the occurrence of any of the events in Section 3B. At the time of application the property owners shall pay the fees in the amount set from time to time by the [municipality]. Section 5. Verification Testing. A. The applicant for a Certificate of I&I Compliance is responsible for arranging a verification test of the property after making application and payment of the fees. The verification testing shall be made either (i) by the [municipality] or (ii) by a licensed plumber or contractor from a list maintained by [municipality] that is approved to conduct the verification. B. Verification Inspection/Testing Procedure. 1. Sump inspections shall be conducted visually. 2. All Service Laterals shall be tested using one of the following procedures. The entire Service Lateral must be tested. The written test results must contain sufficient information to establish the address and identity of the specific Service Lateral being tested. a. Hydrostatic (water) test. The Sewer Service Lateral is tested with each opening tightly plugged, except the highest opening to which a standpipe must be connected to allow a pressure head of 5 feet (60 inches) to the Sewer Service Lateral. The diameter of the standpipe must be no greater than 4 inches and no less than 2 inches. The standpipe and Service Lateral must be entirely filled with water to the top of the standpipe until the level is stable for 5 minutes, and the test may then begin. Once the test begins there may be no more water added to the standpipe. b. Air test. The Sewer Service Lateral is tested with each opening tightly plugged. Apply pressurized air to the test area until there is a uniform gauge pressure of approximately 4 psi. The air pressure must be maintained at 3.5 to 4 psi for 2 minutes until it stabilizes, and the test may then begin. The minimum starting air pressure for the test is 3.5 psi. Once the test begins there may be no more air pressure added to the Service Lateral. 3. The Sewer Service Lateral shall be thoroughly cleaned prior to the testing.

4 4. The property owner shall submit written report of the contractor on the condition of the Service Lateral or sump to the [municipality] department for review. 5. An inspection is presumed valid for a period of six (6) months from the date of inspection. If the property owner fails to obtain a Certificate of I&I Compliance within the six (6) month period, the [municipality] in its sole discretion may require the property owner to obtain another inspection before issuing a Certificate of I&I Compliance. C. Service Lateral Inspection Criteria. 1. A property complies with the provisions of this section if the inspection verifies all of the following conditions: a. The Service Lateral is free of roots, grease deposits, and other solids which may impede or obstruct the transmission of sewage. b. There are no improper or illegal connections to the building Service Lateral such as sump pumps, down spouts or area drainage facilities. c. All joints in the building Service Lateral are tight and sound to prevent the exfiltration of sewage and the infiltration of groundwater, storm water and rain water. d. The Service Lateral is free of structural defects, cracks, breaks, or missing portions and the grade is reasonably uniform without major sags or offsets. e. The Sewer Service Lateral passes the verification testing if it meets the following criteria: 1. Hydrostatic (water) test: If there is no discernable water level loss in the standpipe after 5 minutes under 5 feet of head pressure. 2. Air test: If the air pressure does not drop more than 1 psi in 5 minutes.

5 Section 6. Compliance and Expiration. A. The [municipality] shall review the submitted written verification inspection and testing report to determine compliance with this Chapter. If the Service Lateral and/or sump comply with the provisions of this Chapter and other related ordinances of the [municipality], the [municipality] shall thereupon issue the Certificate of I&I Compliance. B. If the Owner replaces or relines the Service Lateral prior to verification testing and submits evidence from the contactor proving the work was done to in compliance with all provisions of this Chapter and other related ordinances of the [municipality], the [municipality] shall thereupon issue the Certificate of I&I Compliance. C. Once a Certificate of I&I Compliance for a Service Lateral is issued, that Service Lateral shall not require inspection for a period of ten (10) years from the date of issuance unless [municipality] has reason to believe the Service Lateral is in a defective condition. D. For houses constructed in the fifteen (15) years prior to an application, the [municipality official] may in his or her discretion approve a Certificate of I&I Compliance without requiring verification testing of the Service Lateral. A visual inspection of the property will still be required. E. A Certificate of I&I Compliance is valid to be used for the transfer of the property. Section 7. Correction Notice. A. If verification inspection and testing discloses that the use of the property is not in accordance with [municipality] sanitary sewer service requirements, a correction notice may be issued by [municipality] requiring corrections to the property to bring it in to compliance. The corrections must be completed no later than sixty (60) days from the date of the Notice of Correction. Upon proof of satisfactory completion of the corrections, a Certificate of I&I Compliance shall be issued. B. A Notice of Correction may be issued by [municipality] permitting transfer of title of the property if the following conditions are met: 1. An agreement by the Owner or Owner s representative has been executed with the [municipality], whereby the Owner or Owner s representative agrees to complete corrections to the property necessary to bring it within compliance of the [municipality] sanitary sewer service regulations within sixty (60) days of the transfer of property, and

6 2. Security to ensure completion of any corrections to the property must be posted with the closing agent in the form of an escrow or with the [municipality] when a closing agent is not involved, at the time of property transfer or closing. Security must be in an amount at least equal to 125% of the retail value of the work necessary for compliance with this Chapter. Escrow must be fully maintained until a Certificate of I&I Compliance is issued. C. The Owner and any real estate agents involved in the transaction are responsible for disclosing the Correction Notice to the transferee and all other persons or entities involved in the transaction. Responsibility for repairing any nonconformance with the sanitary sewer service regulations runs with the land and not only rests with the owner or transferor but is also an obligation of the transferee of the property. Section 8. Failure to Comply; Penalty. A. Property owners not in compliance with this Ordinance will be charged a monthly surcharge. B. A surcharge of $ per month is hereby imposed and added to every sewer billing to property owners who are not in compliance with this Ordinance. The surcharge shall be levied monthly on properties not complying with the Ordinance. This charge shall cease when the property has been inspected and a Certificate of I&I Compliance is issued by [municipality].
