SECTION 737 - GEOSYNTHETICS (Last Revised September, 2016) QUALITY ASSURANCE PROGRAM. The Department maintains a Quality Assurance (QA) program for geosynthetics appearing on the Approved List. For monitoring purposes, the Geotechnical Engineering Bureau (GEB) will select and evaluate geosynthetic material delivered to project sites to compare its properties to those properties determined at the time of the product's initial approval, which may indicate a change has occurred in the manufacturing process or Quality Control (QC) process.
A.If selected, a QA sample of the following sizes of geosynthetic material will be obtained by a Departmental Geotechnical Engineer and will be submitted for testing:
1.§737-01 Geotextiles: 3 yd2 QA sample.
2.§737-02 Geomembranes: 4 yd2 QA sample.
3.§737-03 Prefabricated Vertical Drains: 10 ft. long QA sample.
4.§737-04 Prefabricated Composite Structural Drain: 3 yd2 QA sample.
5.§737-05 Prefabricated Composite Integral Abutment Drain: 3 yd2 QA sample.
6.§737-06 Prefabricated Composite Edge Drain: 6 ft. long QA sample.
B.The following scenarios may develop as a result of the QA testing.
1.The properties are shown to be comparable to those originally determined, within the statistical validity of the test. No action will be taken.
2.The properties are shown to be significantly different than originally determined.
a.If the results are within the acceptable minimum for approval, contact with the manufacturer will be made by the Geotechnical Engineering Bureau to determine what has changed.
b.If the results are below the minimum acceptable for approval, the product’s status on the NYSDOT TECHNICAL SERVICES APPROVED LIST OF GEOSYNTHETICS FOR HIGHWAY CONSTRUCTION - GEOTEXTILES (Approved List) will be re-evaluated. The manufacturer will be notified of the review.

TABLE 738-1 HYDRODYNAMIC SEPARATORS TREATMENT FLOW RATE Treatment flow rate 738-0101 Up to 1.0 cfs 738-0102 Over 1.0 cfs up to 2.0 cfs 738-0103 Over 2.0 cfs up to 2.8 cfs 738-0104 Over 2.8 cfs up to 3.8 cfs 738-0105 Over 3.8 cfs up to 5.0 cfs 738-0106 Over 5.0 cfs up to 7.0 cfs 738-0107 Over 7.0 cfs up to 10.0 cfs 738-0108 Over 10.0 cfs up to 15.0 cfs 738-0109 Over 15.0 cfs up to 25.0 cfs BASIS OF APPROVAL.
A.For consideration of placement on the Approved List, the manufacturer shall submit the following information for each SWTD type:
1.Total Suspended Solids (TSS) Removal. The manufacturer must submit laboratory test documentation verifying that the SWTD meets the TSS removal goal (50% removal efficiency). Laboratory testing procedures used to determine a SWTD’s ability to remove TSS shall be as described in either the:
a.New Jersey Department of Environmental Protection Laboratory Protocol to Assess Total Suspended Solids Removal by a Hydraulic Sedimentation Manufactured Treatment Device (the New Jersey Protocol). The submitted tests must be conducted by a laboratory;
1.certified by a National Environmental Laboratory Accreditation Program (NELAP),
2.ISO recognized accreditation body, or
3.an independent or in-house New Jersey Corporation for Advanced Technology (NJCAT) approved laboratory to conduct the specific test methods described in the protocol. Refer to the New Jersey Protocol for addition information on laboratory and test requirements.
b.Washington State Department of Ecology’s Technical Guidance Manual for Evaluating Emerging Stormwater Treatment Technologies – Technology Assessment Protocol – Ecology (TAPE) (WA State Manual) . The submitted tests must be conducted at a Washington State Department of Ecology (Ecology) approved Stormwater Technology Evaluation Facility using the protocol described in the WA State Manual. Refer to the WA State Manual for additional information on evaluation facility and test requirements.
2.Flow Capacity. The flow capacity shall be the Maximum Treatment Flow Rate the system can pass while removing at least 50% TSS.
740-01 Thru 740-04 for Site Manager Use
NEW YORK STATE DEPARTMENT OF TRANSPORTATION Section 700 STANDARD SPECIFICATIONS (USC) January 1, 2026 VOLUME 4 The manufacturer must submit laboratory test results verifying that the SWTD meets the TSS removal goal (at least 50% TSS removal efficiency) at the specified flow rate. Further, the manufacturer must submit evidence that the SWTD has been certified to remove at least 50% TSS at the specified flow rate.
3.Manufacturer’s Information. The manufacturer’s cut sheets, installation details, and operations and maintenance manuals for each SWTD type.
4.Third Party Verification. The manufacturer shall also submit:
a.A verification report from the NJCAT and certification from the New Jersey Department of Environmental Protection (NJDEP), based on laboratory testing, documenting that the SWTD meets the technology performance criteria. The verification report must inclu de the NJCAT verification seal and/or letter of acceptance, or
b.An approved Technical Evaluation Report (TER) that verifies the product has been certified by the State of Washington Technology Assessment Protocol – Ecology (TAPE) program with a General Use Level Designation (GULD). Approved SWTDs will be added to the Approved List.
B.Five Year Approved List Renewal. Every five (5) years, the Department must receive:
1.a letter from the manufacturer certifying that no changes have been made to the stormwater treatment device, manufacturer, or manufacturing location, and
2.updated Approved List package (see items 1-5 under Basis of Approval),
3.any changes to the device,
4.renewal to NJCAT and or TAPE list. If the approved list application package and letter are not received, the product may be removed from the Approved List. Further, an approved stormwater treatment device may be removed from the Approved List at any time if the Department is not notified in writing of any manufacturing or material changes as stated above. BASIS OF ACCEPTANCE . SWTD products will be accepted based on the SWTD brand name and model appearing on the Approved List for the intended flow rate and pollutant removal efficiency, and the submission of a material certification for the SWTD stating that the product conforms to the specification and is the same model that appears on the Approved List.
