1 Rehabilitation of Sanitary Sewer Collection Systems Dan Beauchamp, P.E. 1

2 Part 41, Sewerage Systems, of the Natural Resources and Environmental Protection Act, PA 451 as amended (NREPA) 2

3 R Rule 33. (1) Before the construction or alteration of a sewerage system or portions thereof, plans and specifications shall be submitted to the Department for review and issuance of a construction permit. 3

4 R (a) "Alteration" means the construction of any modification or addition to an existing sewerage system which changes the process or system capacity 4

5 1. Cured in Place Pipe (CIPP) 2. Slip Lining 3. Pipe Bursting 4. Manhole Rehabilitation 5. Open Cut Repairs (replacing same size with different pipe material) 6. General sewer maintenance 5

6 Consists of lining the inside of a pipe with an epoxy resin 6

7 The change in the pipe diameter from the existing pipe is usually less then 5%, and Does not significantly reduce the hydraulic capacity of the sewer 7

8 A Part 41 permit may be required - contact the local district office of the DEQ for determining if a Part 41 permit is necessary 8

9 An appropriately sized liner pipe is inserted into an existing pipe 9

10 The change in the Pipe Diameter is usually greater then 5% of the existing pipe diameter size The change in pipe diameter will significantly decrease the hydraulic capacity of the collection sewer for that run 10

11 A Part 41 permit will be required due to the change in the hydraulic capacity of the sewer 11

12 Insertion of a cone shaped bursting head that fractures the old pipe and pushes the fragments into the surrounding soil A new pipe is pulled into place 12

13 Typically, the pipe inserted is of larger diameter than the existing sewer pipe, which will alter the hydraulic capacity of the sewer A Part 41 permit is required, due to the change in the hydraulic capacity of the sewer 13

14 Chimney repair Sealing cracks and joints Replacing covers Repairing sewer channel 14

15 A Part 41 permit IS NOT required Manhole rehabilitation does not alter the hydraulic capacity of the sewer 15

16 A Part 41 Permit is NOT required IF: The new sewer pipe is the same diameter as the existing pipe different material may be used 16

17 Part 41 Permit Is NOT required 1. Cleaning/Jetting 3. Grouting 2. Televising 4. Smoke testing 5. Manhole inspection 6. Open cut sewer repair replacing a pipe section or two 17

19 Stormwater Asset Management Wastewater $97 million available FY14 (grants and loans) 19

20 A city, village, county, township, authority, or other public body, including an intermunicipal agency of 2 or more municipalities, authorized or created under state law; or an Indian tribe that has jurisdiction over construction and operation of sewage treatment works or other projects qualifying under section 319 of title III of the federal water pollution control act, 33 USC Public bodies (other than cities, villages, counties, and townships) and Authorities applying for SAW grants or loans must indicate the relevant authorizing statute in the application. 20

21 Development of wastewater and stormwater asset management plans Planning and design of wastewater and stormwater projects Development of stormwater management plans (MS4, NPS, SAW) Testing and demonstration of innovative technology 21

22 New $2 million grant cap per community - 90% grant/10% local match up to $1 million - 75% grant/25% local match for 2 nd million - 100% grant to disadvantaged communities, municipalities in receivership, municipalities operating under an emergency manager, municipalities operating under a financial consent agreement 22

23 Construction of projects identified in approved stormwater management plan Construction of projects identified in approved asset management plan Construction of projects of proven innovative technology 23

24 Costs for construction No Davis-Bacon No public participation requirements $30 million max for loans with $10 million per applicant for FY14 Interest rate 2.5% for FY14 24

25 Final application available Oct. 1, 2013 Accepted on or after December 2, 2013, no prior review 120-day DEQ review period Grants funded first-come, first served 25

26 Complete inventory of system assets Condition assessment is allowed but reasonable assumption of some assets is acceptable Cleaning/Televising entire system is not expected Wastewater must show significant progress towards funding structure w/in 3 years initial rate increase to close 10% of gap w/in 3 years with 5 year plan to eliminate full gap Stormwater must be implemented w/in 3 years 26

27 Wastewater applicants agree to NPDES Asset Management conditions in their next permit reissuance NPDES permit language on our website 27

28 Businesses not eligible, only municipalities Must address a problem or need (water quality issue, lower costs, less energy, green innovative) Must meet one of four categories Pilot study work plan must be submitted with grant application If demonstration is determined feasible grantee must agree to construct a full-scale project 28

29 Must meet one or more of the following: The technology has not been previously used in Michigan or the region, if influenced by climate The technology has not been previously used in the United States, if independent of climate influences The technology is an application of an existing technology applied to a different media (e.g. a water supply treatment technology applied to the wastewater field) The technology is an application of an existing technology applied to a different pollutant (e.g. previously used to address pollutant X, proposed to address pollutant Y ) 29
