Technical Requirements/Specification Sheet

Aberdeen Test Center

Description of Purchase: Wastewater Process System: Dye penetrant inspection involves the generation of wastewater that cannot be disposed of as normal wastewater due to contamination with oil, and marine pollutants. This system will filter the water before being disposed of.

Technical Requirements:

Post emulsifiable hydrophilic dye penetrant inspection utilizes a petroleum distillate based dye penetrant and a emulsifier. The SDS information on these two items further details the following substances:

Petroleum distillates Castor oil Hexanedioic acid (Adipic acid) Triphenyl Phosphate Coumarin 2-methyl-2,4-pentanediol Poly-alpha-Omega-Hyrdroxy

These substances, along with a majority volume of water are to be disposed of using municipal sewer. The effluent must be treated in a manner meeting EPA regulations prior to discharge. Of these substances, wastewater disposal of Poly-alpha-Omega-Hyrdroxy, castor oil, and petroleum distillates are regulated.

Tripenyl Phosphate is not yet regulated but may be soon. The technical requirement of the wastewater treatment system is to meet the applicable EPA regulations as defined in CFR 40. Further detail is provided below:

In 2014, the United States Environmental Protection Agency added Triphenyl Phosphate TPhP to its list of Toxic Substance Control Act Work Plan for Chemicals on the basis that the compound has exhibited "acute and chronic aquatic toxicity," "moderate bioaccumulation potential," and "moderate environmental persistence” (https://www.epa.gov/sites/default/files/2020-09/documents/casrn_115-86- 6_triphenyl_phosphate_tpp_final_scope.pdf)

There may be releases of TPhP from industrial sites to wastewater treatment plants (WWTP), surface water, air and landfill. Articles that contain TPhP may release TPhP to the environment during use or through recycling and disposal. Currently, TPhP is not currently regulated as a hazardous waste but TPhP is one of the 20 chemicals EPA designated as a HighPriority Substance for risk evaluation under TSCA (84 FR 71924, December 30, 2019). Designation of TPP as a high priority substance constitutes the initiation of the risk evaluation on the chemical. (https://www.ecfr.gov/current/title-40/chapter-I/subchapter-R/part-721/ subpart-E/section-721.11592)

Poly-alpha-Omega-Hyrdroxy is regulated by 40 CFR 721.11592 to no more than 34 part per billion final concentration entering United States waters. The effluent from ATC’s dye penetrant system starts at approximately 1% concentration, and is treated at a municipality water treatment plant before discharge into the waters of the United States. Wastewater monitoring is required regardless of effluent concentration, but a written action plan requiring EPA approval is required for concentrations exceeding 34 PPB. The purpose of the Ozone generator water treatment system is to chemically destroy or convert the Poly-alpha-Omega- Hyrdroxy and reduce the concentration below 34 PPB.

Total footprint of the system must fit in a space of 36" by 48" and must run on 120/240V single phase, or 208V 3 phase. The dye penetrant station is not set up for re-use of wastewater. Systems for re-use of wastewater are not acceptable.
