Protecting Trenchless Technology
The traditional way of repairing a deteriorated pipe is to dig it up and replace it with a new one. Thanks to trenchless technology, pipes can be recycled, rehabilitated and even replaced without disrupting and digging up the earth. As with any new technology, trenchless methods have been challenged over the years, and NASSCO has worked hard to build awareness for these cost-effective and ecologically sound solutions to assure the continued acceptance and growth of all trenchless technologies.

Styrene Safety Research Phase 4 – Assessing the Impact of CIPP Cure Water on POTW Biological Treatment included literature review, market research, and lab testing by Buried Asset Management Institute-International.
NASSCO Files Code Appeal with ICC – NASSCO filed an appeal with the International Code Council (ICC) regarding an International Plumbing Code (IPC) errata that retroactively imposed the mandatory use of hydrophilic rings or gaskets in cured-in-place rehabilitation of building sewer piping and sewer service laterals. NASSCO believed that the issuance of the errata was improper as it contravened the ICC code development processes and procedures, including the requirement for an open and transparent process. Following the ICC Appeal Board meeting, which included a verbal presentation by NASSCO, the ICC Appeal Board agreed with NASSCO’s position and the errata was revoked/not issued in connection with the 2024 and 2027 IPC.

Styrene Safety Research Phase 2 – Evaluation of Air Emissions from Polyester Resin CIPP with Steam Cure included field studies conducted by the Trenchless Technology Center (TTC) at Louisiana Tech University.
Reversal of CIPP and Trenchless Technologies Ban – After nearly two years of advocating for the removal of language in the Uniform Plumbing Code (UPC) that banned the use of cured-in-place pipe and other trenchless technologies to replace cast iron soil pipes and fittings, NASSCO’s Lateral Committee received a decision from the IAMPO Board of Directors that reversed this ban.

Styrene Safety Research Phase 1 – Evaluation of Potential Release of Organic Chemicals in the Steam Exhaust Using the CIPP Method was a literature review conducted by CUIRE at the University of Texas – Arlington
2011
Government Review Request – The National Toxicology Program of Health and Human Services listed styrene as a potential carcinogen. NASSCO members worked closely with the styrene industry to request a government review of the science behind the findings. Ultimately a congressional committee authorized funding of the study by the National Academy of Science.
2008
NASSCO Challenge of Proposed Changes to OSHA – Proposed changes to OSHA confined space entry regulations were challenged by NASSCO. If reclassified to “new construction”, routine maintenance jobs would have meant additional job site requirements, costing the industry roughly $7.5 million per year. NASSCO testified at congressional hearings to request that OSHA classify rehabilitation work as maintenance. We were successful.
2003
NASSCO Resolves Costly Government Regulation – A CCTV manufacturer attempted to get government regulations revised for explosion-proof cameras in a sanitary sewer environment. The proposed revisions would have cost contractors up to a hundred million dollars. Thanks to the unification and determination of NASSCO members to do what is best for our workers and communities, the issue was successfully resolved.

NASSCO Helps Prevent Ban of Acrylamide Grout – In the late 1990s NASSCO worked closely with the EPA to prevent a proposed ban of acrylamide grout, an effective product to address I/I. Fully supported by contractor, supplier and professional members of NASSCO, many of whom were competitors who came together to do what’s right, the issue was finally resolved in 2002 with a rejection of the proposed ban.
