DRAFT
SUFFOLK COUNTY DECENTRALIZED WASTEWATER SYSTEM UPGRADE AND
NITROGEN MITIGATION PROGRAM
CRITERIA & RATING SYSTEM
Rev. Draft October 3, 2012
PROJECT CRITERIA
Must meet the first factor below, and 5 of the remaining 6 factors below: Yes No
1. Project complies with Appendix A of SCDHS Commercial Construction Standards which currently allows for
advanced subsurface nitrogen removal for flows of up to 15,000 gpd (as of October 2012) for commercial projects
or residential clusters (1,000 gpd or greater), or is in conformance with other current SCDHS Construction
Standards or has otherwise been approved by the SCDHS, and, if not passive, evidence of an annual maintenance
contract under an approved management company has been provided (under SPDES permit, or within an
acceptable management district created in accordance with state law).
2. Project is consistent with at least one of the following plans: Suffolk County’s Comprehensive Plan, Long Island
Regional Economic Development Council Strategic Plan, estuary plans, the draft Comprehensive Water Resources
Management Plan, Local Waterfront Revitalization Plans adopted by NYS, or applicable community-based locally-
adopted municipal plans that have also been appropriately referred to the Suffolk County Planning Commission.
For purposes of decentralized systems, this can be demonstrated by a showing that the project protects or
improves the quality of drinking waters within the 50-year groundwater-contributing area to public supply wells, or
areas served by private wells, or project protects or improves the quality of nitrogen-sensitive waterbodies within the
25-year groundwater travel time to surface waters and tributaries of Long Island Sound, South Shore Estuary
Reserve, or Peconic Estuary.
3. Project applicant demonstrates the financial capacity to successfully implement project & demonstrates the
experience to successfully carry out the project.
4. Project applicant demonstrates the ability to start the construction within 12 months of contract execution.
5. Project or site does not have current or foreseeable access to existing county, municipal or other
community/decentralized sewage systems.
6. Site and its proposed use(s) will not compromise or reduce any environmentally sensitive natural habitats such as
wetlands, rare upland plant/forest habitats, habitats of endangered, threatened and/or special concern species
pursuant to Federal/New York State listings.
7. Project substantially addresses pre-existing sewage flow, rather than sewage flow from new development for which
sewage treatment is necessary due to SCDHS density restrictions.
PROJECT CHARACTERISTICS Score
A. Financial Leverage (20 points max)
1. Project demonstrates private and/or non-county public investment. (20% match: 5 points; 30% match: 10 points; 40%
match: 15 points; 50% match: 20 points)
B. Environmental Impact (80 points max) ** Nitrogen % reduction as compared to that from conventional septic systems
1. Project complies with the Total Maximum Daily Load (TMDL) requirement, or significantly reduced nitrogen load (50% or
more**) in an area subject to a nitrogen TMDL. (8 points)
2. Project demonstrates a significant surface water benefit (minimum 50% reduction of nitrogen**) within 10-year travel time
to sensitive water body (Peconic Estuary, LI Sound, etc.) (4 points) or 2-year travel time to sensitive water body (8 points)
3. Project demonstrates a significant drinking water benefit (minimum 50% reduction of nitrogen** within 10-year travel time
to public water supply well, or in an area predominantly served by private wells) (4 points) or within a 2-year travel time to
public supply wells. (8 points)
4. Project serves nonconforming lots in areas that were developed prior to the establishment of Article 6 of the Suffolk
County Sanitary Code and have remained unsewered – majority of lots < 1 acre (4 points) or majority of lots < ½ acre (8
points)
5. Project reduces nitrogen discharge to below 25 mg/l (2 points), 10 mg/l (4 points) or 5 mg/l (8 points)
6. Project replaces a cesspool or failing system (8 points)
7. Project demonstrates attainment of advanced environmental performance credentials (i.e. LEED) and/or energy efficient
measures and/or adhere to Low-Impact Development or Better Site Design and/or employ green infrastructure and/or
water conservation measures (e.g., stormwater management, green roofs, repurposing wastewater). (8 points)
8. Project is located in a flood zone and upgrades a pre-existing non-conforming system or recharges pre-existing sanitary
wastewater out of the flood zone. (8 points)
9. Project promotes an integrated watershed approach (e.g., a pilot project with demonstrated goal of meaningful
subregional water quality improvement). (16 points)
Total Score (maximum = 100 points)
