Public hearings set on proposed wastewater discharge rules

The North Carolina Environmental Management Commission has scheduled a series of public hearings in select cities beginning next month on proposed PFAS and 1,4-dioxane monitoring and minimization rules.

In all, six hearings have been set, three of which will focus on proposed rules for discharges of three per- and polyfluoroalkyl substances through wastewater into North Carolina’s surface waters and three on proposed rules for monitoring and minimizing 1,4-dioxane in wastewater discharges from certain facilities into surface waters.

A public comment period for each set of proposed rules will kick off on March 16 and continue until June 15.

Under the proposed PFAS rules, all major and minor industrial direct dischargers, and significant industrial users that discharge to publicly owned treatment works, would be required to monitor and implement “minimization activities required to eliminate or significantly reduce” discharges of PFOS, PFOA, and GenX within a period of anywhere between three and five years.

Discharge limits for those specific PFAS have yet to be determined.

PFAS exposure has been linked to a number of adverse health impacts to people, including thyroid disease, increased cholesterol, liver damage, and different types of cancers.

More than 3 million North Carolinians are estimated to drink tap water containing PFAS levels above the U.S. Environmental Protection Agency health-based standard scheduled to go into effect in the coming years, according to the N.C. Department of Environmental Quality.

Public hearings on the proposed rules for the three PFAS are scheduled as follows:

• April 7 at 6 p.m. in Ferguson Auditorium, AB-Tech Community College, 19 Tech Drive, Asheville.
• April 20 at 6 p.m. in the Archdale Building, ground floor hearing room, 512 N. Salisbury St., Raleigh. Public parking will be available after 5 p.m. at parking deck 64 across North Salisbury Street from the Archdale Building.
• April 23 at 6 p.m. in Wilmington City Hall at Skyline Center, first floor conference center, 929 North Front St., Wilmington. Parking is available in the south lot using the Brunswick Street entrance. Attendees requiring American with Disabilities Act access should park in the visitor lot.

Written comments are being accepted by email to publiccomments@deq.nc.gov with the subject title “PFAS minimization” or by mail to Karen Preston, DEQ-DWR NPDES Permitting Section, 1617 Mail Service Center, Raleigh, NC 27699-1617.

Comments will be accepted on the proposed rule adoptions and associated regulatory impact analysis. The commission is also accepting comments on specific questions including:

• Whether it would be scientifically defensible and advisable to establish a screening threshold above the lowest reporting concentration for PFOS, PFOA and GenX that could serve as a trigger for ongoing monitoring and minimization requirements.
• Whether the applicability of the PFAS monitoring and minimization rule should be limited to industrial dischargers associated with a standard industry classification (SIC) or North American Industry Classification System (NAICS) codes known to be linked to PFAS use or discharge.

Hearings on proposed rules for monitoring and minimizing 1,4-dioxane, a federally deemed likely human carcinogen, in wastewater discharges into surface waters from certain facilities have been scheduled for the following dates:

• April 9 at 6 p.m. in the Catawba County St. Stephens Branch Library, 3225 Springs Road, Hickory.
• April 14 at 6 p.m. at Fayetteville Technology Community College, Tony Rand Student Center multipurpose room, 2220 Hull Road, Fayetteville.
• May 12 at 6 p.m. in the Percy H. Sears Applied Technologies Building Auditorium, Guilford Technical Community College, 1201 Bonner Drive, Jamestown.

Written comments on the proposed rules for 1,4-dixoane may be submitted via email to publiccomments@deq.nc.gov with the subject heading “1,4-dioxane minimization,” or by mail to Bridget Shelton, DEQ-DWR Planning Section, 1611 Mail Service Center, Raleigh, N.C., 27699-1611.

The EMC will also be accepting specific comments on the proposed 1,4-dixoane minimization rules to include:

• Whether a screening threshold above the lowest reported concentration (currently 1 microgram per liter) for 1,4-dioxane would be appropriate as a trigger for ongoing monitoring and minimization planning.
• whether the applicability of the 1,4-dioxane monitoring and minimization rules should be expanded beyond the currently proposed scope of dischargers with certain standard industry classification or North American Industry Classification System codes to include all industrial dischargers.

Sign-in and speaker registration will begin at 5 p.m. at each of the hearings.

Based on attendance, speaking time may be limited to allow everyone an opportunity to be heard. The commission will accept written comments and copies of prepared remarks at each hearing.
