Rehabilitation of Sanitary Sewer Collection Systems
1
Dan Beauchamp, P.E.
Part 41, Sewerage Systems, of the Natural Resources and Environmental Protection Act, PA 451 as amended (NREPA)
2
R 299.2933
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
R 299.2931
(a) "Alteration" means the construction of any modification or addition to an existing sewerage system which changes the process or system capacity
4
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
Consists of lining the inside of a pipe with an epoxy resin
6
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
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
An appropriately sized liner pipe is inserted into an existing pipe
9
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
A Part 41 permit will be required due to the change in the hydraulic capacity of the sewer
11
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
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
Chimney repair
Sealing cracks and joints
Replacing covers
Repairing sewer channel
14
A Part 41 permit IS NOT required
Manhole rehabilitation does not alter the hydraulic capacity of the sewer
15
A Part 41 Permit is NOT required IF:
16
The new sewer pipe is the same diameter as the existing pipe different material may be used
17
1. Cleaning/Jetting
2. Televising
Part 41 Permit Is NOT required
3. Grouting
4. Smoke testing
5. Manhole inspection
6. Open cut sewer repair replacing a pipe section or two
18
Stormwater
Asset Management
Wastewater
$97 million available FY14 (grants and loans)

“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 1329.”
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.
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
New $2 million grant cap per community
- 90% grant/10% local match up to $1 million - 75% grant/25% local match for 2nd million - 100% grant to disadvantaged communities, municipalities in receivership, municipalities operating under an emergency manager, municipalities operating under a financial consent agreement
22
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
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
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
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
Wastewater applicants agree to NPDES Asset Management conditions in their next permit reissuance
NPDES permit language on our website
27
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’)
