Other 2023 N.C. Environmental Legislation

December 19, 2023. The previous post covered significant water quality legislation enacted by the North Carolina General Assembly in 2023. This post briefly summarizes other 2023 environmental legislation.

AIR QUALITY. The legislature put two provisions in the Appropriations Act of 2023 (House Bill 259) to prevent state agencies from adopting rules intended to reduce emissions of greenhouse gasses such as carbon dioxide (CO2) in the state. Other air quality provisions expedite permitting and construction of new or expanded sources of air pollutants.

Prohibit cap and trade programs for CO2 emissions.  House Bill 259, Sec. 12.5,  prohibits any state agency  from requiring electric utilities to participate in a cap and trade program for CO2 emissions. The provision targeted proposed state rules that would have required N.C. electric utilities to  participate in a multi-state cap and trade program (the Regional Greenhouse Gas Initiative) to reduce CO2 emissions. For more on the proposed RGGI rules see an earlier post.   The broadly written 2023 provision prohibits any state cap and trade program for reduction of greenhouse gas emissions from electric utilities.

Prohibit emission standards for new vehicles. A new statute section, G.S. 143-215.107F, prohibits adoption of emissions standards for new motor vehicles including rules intended to increase the number of zero-emission vehicles in North Carolina. The legislation responds to Governor Cooper’s Executive Order 271 which directed the Department of Environmental Quality (DEQ) to  draft rules modeled on  California’s Advanced Clean Truck rule. The California ACT rule requires truck manufacturers to gradually  increase the percentage of zero-emission medium and heavy duty trucks sold in that state over several years.  N.C. DEQ had already completed draft clean truck rules and a regulatory impact analysis estimating the economic costs and benefits of the proposed rules as required by EO 271.  The rules had not yet been presented to the Environmental Management Commission (EMC) to begin the rulemaking process.

The economic impact analysis  for the draft North Carolina clean truck rules showed a significant net economic benefit to the state. The analysis considered two alternative timelines for zero-emission truck goals. Earlier implementation resulted in a net economic benefit to the state of $175.6 million to  $880.5 million (depending on a range of estimated health benefits). Beginning implementation a model year later resulted in a net benefit of $162.3 million to $865.9 million.

Limit the vehicle emission inspection program. Some background — As required by the Clean Air Act, North Carolina has a State Implementation Plan (SIP) for ozone pollution describing how the state will meet the federal ozone standard.  N.C.’s  ozone SIP counts pollution reductions associated with identifying and correcting faulty vehicle emission systems toward meeting the standard. The  U.S. Environmental Protection Agency (EPA)  approved N.C.’s current ozone SIP based on vehicle emission inspections in 19 N.C. counties. The SIP included counties in the emissions inspection program based on the potential for vehicles registered in those counties to contribute to an exceedance of the ozone standard.

The 2023 state law directs DEQ to eliminate emissions inspections in 18 counties and request  EPA  approval of a revised ozone SIP that only requires emissions inspections in Mecklenburg County. The impact of a revised SIP on North Carolina’s ability to meet the ozone standard statewide will likely turn on factors such as the declining percentage of vehicles with older emissions control equipment and increases in low or zero emission vehicles. The law allows one year for DEQ to submit the revised SIP to EPA for approval; EPA then has 18 months to approve or disapprove the revised SIP. Emission inspections will continue to be required  in all 19 counties until EPA approves a revised SIP.

Allow expansion of existing air emissions source without prior permitting. Another provision in House Bill 259 amends G.S. 143-215.108A to allow “the construction (but not operation) of a new air contaminant source, equipment, or associated air cleaning or emissions control devices prior to permit issuance”.  The provision includes exceptions for sources requiring a Prevention of Significant Deterioration (PSD) permit; those covered by specific Clean Air Act sections regulating hazardous air pollutants; and sources in non-attainment areas. Even with the exceptions, it is not clear the provision allows the state to fully comply with Clean Air Act permitting obligations.  Allowing construction of a pollution source without prior review also creates a risk that the facility will invest in equipment that does not meet standards necessary to be permitted for operation.  That creates the  related risk that state permitting staff will be pressured to approve air pollution emission sources  that do not meet operating standards because of the prior investment.

Salary bonuses based on quick processing of Title V permits. Another budget provision creates a program to give salary bonuses to DEQ air quality permitting  staff who process Title V air quality permit applications within specified time frames.  The provision raises ethical questions given the creation of financial incentivizes for permit staff to approve permits more quickly. In  recognition of that concern, the provision directs the EMC  to adopt quality control standards to ensure permit decisions comply with the law. The obvious quality control standard will be consistency with permitting processes and air quality standards. The question will be how to provide adequate oversight of DAQ permit writers to ensure that incentives for quick permit action do not undermine adequate permit review and result in flawed permit decisions.

The  bonus provision doesn’t neatly align with existing Title V permitting practices in North Carolina. The legislation is written as if each facility’s Title V permit application (or renewal) is handled by an individual permit writer as part of a single facility-wide permit review. In reality, the Title V permitting process has adapted to industry needs by dividing review of multiple pollution sources at a single facility among  permit staff who specialize in those sources and associated pollution controls. Review of the different pollution sources can also move on different tracks, allowing some to be approved more quickly than others. It remains to be seen whether shifting to the model of permit review necessary to implement the bonus program (review of all sources at a facility in a single review) will actually benefit  permit applicants.

The new provision gives the EMC authority to exclude an individual DAQ employee from the bonus program based on  overall permitting performance. Doing so would have implications under state personnel law that have not yet been discussed.

Set permit processing times for Title V permits. House Bill 259, Section 12.11,  also amends G.S. 143-215.108(d)(2) to set new timelines for DAQ to act on an application for modification of  a Title V permit. The law now requires DAQ to issue, deny or publish for public comment a complete application for a  minor modification of a Title V permit within 90 days. It requires DAQ to issue, deny or publish for comment a complete application for a major modification of a Title V permit within 270 days.  The provision also repeals language in G.S. 143-215.108 that extended the time allowed to act on a Title V permit if the EPA Administrator objected to issuance of the permit.

Create Title V permit exemption for “non-major” research and development activities. Another  provision in Sec. 12.11 directs the EMC to create a Title V permit exemption for “non-major research and development activities”  consistent with a 1995  EPA  white paper on streamlining Title V applications.  In part, the white paper describes how permitting agencies should evaluate a research and development activity under Title V. The paper reflects EPA’s  assumption that many  R & D activities are independent of manufacturing operations and standing alone would not be major pollution sources that would trigger Title V permitting. But the paper also notes that R & D  activities co-located with manufacturing and contributing to the facility’s total air emissions would need to be included in the Title V permit. In other words, the paper doesn’t create an exemption; it describes how permitting agencies should apply Title V  to different types of R & D facilities.

The language of the new state provision misses the nuance of the white paper and requires the EMC to develop a Title V exemption for research and development activities. On the other hand, it directs the new EMC  rules to include “allowance levels and minor permit modification thresholds” that would allow a permitted Title V facility to cover R & D activity by giving DAQ notice of a minor permit modification. That language seems to describe a streamlined process for modifying a Title V permit rather than a Title V permit exemption. The EMC will need to sort out the actual intent of the law in the rulemaking process.

SOLID WASTE

Disposal of lithium- ion batteries. House Bill 600, Section 19, amends G.S. 130A-309.10(f) to prohibit landfill disposal and incineration of lithium-ion batteries. The legislation also directs DEQ to study whether it is appropriate to allow landfill disposal of some lithium-ion batteries based on the size of the battery.

Disposal of photovoltaic cells and components. The same section of House Bill 600 amends G.S. 130A-309.10 by adding a new subsection that prohibits disposal of photovoltaic cells in an unlined landfill. Under the new provision, all photovoltaic cells and  components that cannot be recycled must be disposed of in a lined municipal or industrial landfill rather than an unlined construction and demolition debris landfill.

GENERAL

Require permits to include statutory or regulatory authority for conditions. House Bill 600, Section 13, adds a new statute section (G.S. 143B-279.4A) requiring DEQ to include in every permit the statutory or regulatory authority for each permit condition. Since the new statute provision has been added to  Chapter 143B (which describes DEQ’s responsibilities as a department), it appears to apply to all DEQ permitting programs.

Prohibit denial of a permit based on failure to obtain another permit, authorization, or certification.  House Bill 259, Section 12.10, adds a new statute section (G.S. 143B-279.18) that prohibits DEQ from denying a permit based on the permit applicant’s failure to obtain another permit, authorization or certification unless that is required by state or federal law.  This provision also appears to apply to all DEQ permit decisions.

Define “administratively complete” for purposes of permit review. Another provision in House Bill 259 adds a definition of “administratively complete” to G.S. 143-213 to describe a permit application that is sufficiently complete to trigger permit processing timelines in statute:

(1) The term “administratively complete” means that all information required by statute, regulation, or application form has been submitted to the Department for the purpose of processing a permit application.

The definition applies wherever the term is used in Chapter 143 Article 21 (Water and Air Resources), Article 21A (Oil Pollution and Hazardous Substance Control), and Article 21B (Air Pollution Control).

N.C. Water Quality Legislation (2023)

December 14, 2023. Having regained a veto-proof majority in the state legislature, the N.C. General Assembly returned to a very aggressive effort to influence environmental rules in 2023. The annual Appropriations Act (House Bill 259), the N.C. Farm Act of 2023 (Senate Bill 582) and the Regulatory Reform Act of 2023  (House Bill 600) all contained provisions weakening existing environmental protections and in some cases preventing adoption of new standards. This post covers the  most significant legislation affecting state water quality protections:

AQUACULTURE PERMITTING

Replace the existing NPDES General Permit for aquaculture operations. The Clean Water Act requires a National Pollutant Discharge Elimination System (NPDES) permit for any release of waste to surface waters.  North Carolina has developed a number of  NPDES “general permits” to cover wastewater discharges from facilities engaged in similar activities and producing wastewater with similar characteristics. NPDES General Permit  NCG530000 covers wastewater from seafood packing and rinsing; aquaculture operations; and other activities producing similar wastewater. A facility can be covered under the general permit by meeting conditions in that permit; otherwise, the facility can apply for an individual NPDES permit tailored to the operation. 

Section 14 of Senate Bill 582 directs DEQ and the EMC to replace the current general permit (in effect since December 1, 2021) with the previous version of NCG530000. Reverting to the earlier permit will eliminate water quality monitoring requirements for nitrogen and phosphorus that were added to the permit in 2021.  Aside from the environmental implications of eliminating water quality monitoring for nutrients released from aquaculture operations, the provision raises another legal question and policy question: Does the provision violate the N.C. Constitution by allowing the legislature to intervene directly in the issuance of environmental permits?

Under the N.C. Constitution, the legislature adopts the laws under which state agencies operate, but responsibility for implementing those laws rests with executive branch agencies like DEQ.  The issuance of an NPDES permit (whether a general permit or an individual permit) is clearly within the authority and responsibility of the executive branch.  A legislative directive to modify or replace a specific permit appears to cross a significant constitutional line.   Aside from the constitutional  issue, legislative intervention in a permitting action sets a precedent for direct political intervention in permit decisions.  

ANIMAL OPERATIONS

Groundwater compliance boundaries for animal operations.  A little background — North Carolina’s groundwater protection program requires a state permit for the release of  pollutants to groundwater. Permitted waste disposal facilities (such as landfills)  have a groundwater  “compliance boundary” that (for most facilities)  extends 250 feet from the waste disposal area. Inside the compliance boundary,  pollutants in groundwater may exceed groundwater quality standards; beyond the compliance boundary, groundwater must meet all standards. Permits require regular groundwater monitoring inside and outside the compliance boundary to ensure groundwater standards are met.

There have long been concerns that animal waste systems such as swine waste lagoons and spray fields may result in groundwater contamination. But unlike other types of waste disposal facilities,  animal waste systems have not been required to routinely monitor for groundwater impacts.  State permits for animal operations have only required groundwater monitoring under very narrow circumstances.

This session, the legislature amended the animal waste system permitting law, G.S. 143-215.10C,  to  require a groundwater compliance boundary at animal operations:

“[animal operations] shall have a compliance boundary as may be established by rule or   permit for various categories of animal waste management systems and beyond which       groundwater quality standards may not be exceeded.”

The provision also directs the Environmental Management Commission  (EMC) to require investigation and corrective action (such as remediation)  if a facility violates groundwater standards beyond the compliance boundary. (See: House Bill 600, Sec.15). The provision may lead to an interesting rule-making process,  since implementation of a compliance boundary and corrective action require groundwater monitoring and animal operations have strongly resisted monitoring in the past.

 1,4 DIOXANE

Health Risk Assessment and Technology Review. The legislature directed DEQ to do a human health risk assessment of 1,4 dioxane in drinking water based on peer-reviewed studies and report back to the legislature by May 1, 2024. The purpose of the state study is unclear.  In 2020, EPA finalized a human health risk assessment for 1,4 dioxane that concluded  1,4 dioxane has  adverse effects on humans and is a likely human carcinogen.  That risk assessment focused largely on worker exposure, although it also considered public exposure to 1,4 dioxane in consumer products and surface water. In July 2023,  U.S. EPA released a Draft Revised Risk Determination for 1,4 dioxane for public comment. The  revised risk determination  evaluates risk associated with additional pathways for exposure, including  exposure to 1,4 dioxane in drinking water. The revised draft risk assessment finds that 1,4 dioxane in drinking water presents an unreasonable risk to human health.

The state study provision also directs the N.C. Collaboratory at UNC-CH to evaluate technologies commercially available to remove 1,4 dioxane from wastewater effluent at different flow volumes and report its findings on the technical and economic feasibility;  limitations of each treatment technology; and a cost benefit analysis to the legislature by May 1, 2024. (See: House Bill 600, Sec. 9)

STORMWATER.  Continuing a ten-year pattern, the legislature amended  state stormwater law to further limit state and local government stormwater control requirements. Most of the stormwater amendments appear in the 2023 Regulatory Reform Act (House Bill 600):

Treatment of stormwater from impervious areas added as part of a redevelopment project.  G.S. 143-214.7(b3)  already prevented stormwater permitting agencies from requiring new stormwater controls for existing developed areas included in a redevelopment project. But the law expressly allowed permitting agencies to require treatment for stormwater from impervious surface added during redevelopment. That authority remains in the law, but the 2023 amendment  inserts new language allowing the developer to  “elect” to provide stormwater treatment for new impervious area  — seeming to create a conflict within the law. As a result, It isn’t clear whether treatment of stormwater from new impervious area can still be required or is entirely optional. (See: House Bill 600, Sec. 2)

Prohibit stormwater permit conditions related to adjacent property.  Under a new subpart added to  G.S. 143-214.7,  DEQ  cannot require a new permit applicant to take any action with respect to an “unaffiliated adjacent property” or condition issuance of a new permit on action to be taken by an existing permit holder with respect to an unaffiliated adjacent property.  It isn’t clear what real world situation the new provision addresses since the state stormwater program has never required a developer to install stormwater controls on adjacent property. The provision may be intended to prevent DEQ from requiring a new development project to adequately treat stormwater entering the development site from another property, but more background will be needed to understand the provision’s impact. (See: House Bill 600, Sec. 2)

Exempt private streets from post-construction stormwater requirements. The provision directs the  EMC to exclude linear transportation projects that are: 1.  part of a common plan of development;  and 2. not constructed by DOT or a municipality from the calculation of built-on area for purposes of stormwater management. As a practical matter, that means private subdivision streets would not be included in calculation of stormwater runoff from the development and as a result the stormwater system would not be sized or designed to manage the stormwater from those surfaces. (See: House Bill 600, Sec. 4).

Exempt airport construction borrow sites and staging areas from Neuse buffer certification requirements. State stormwater standards already provided special consideration for  airport facilities particularly with respect to mandatory stream buffers. The new provision redefines “airport facilities” to include borrow sites and staging areas for airport-related construction . Under the provision, construction of borrow sites and staging areas within a stream buffer will not require prior approval normally granted through issuance of a certification for the activity under 15A NCAC 2B.0611(b). The provision requires mitigation of the buffer impacts consistent with the Neuse buffer rules, but it is not clear how buffer impacts will be measured and mitigation calculated in the absence of DEQ certification.  (House Bill 600, Sec. 21).

Timelines for review of state stormwater permits. Amends G.S. 143-214.7 to add timelines for DEQ review of stormwater permit applications. DEQ staff must do a completeness review within 10 days of receiving the application. If the application is complete, a 70-day technical review period begins. The provision also sets out specific requirements and timelines for DEQ to request additional information once the technical review begins. The provision directs that permits should be issued for a term not to exceed 8 years. (See: House Bill 259, Sec. 12.12.)

WATER SUPPLY WATERSHEDS

 Water supply watershed redevelopment.  Amends G.S. 143-214.5(d3) to allow redevelopment of nonresidential properties to exceed water supply watershed density limits without providing stormwater treatment for any increased density (as compared to the previous land use). As amended, the law would allow redevelopment at increased density without stormwater treatment based on either the preexisting density or the increase in density. (See: House Bill 600, Sec. 1)

Density exception for two local government jurisdictions. The legislature created a new exception for Iredell County and the Town of Mooresville that would allow up to 20% (instead of 10%) of the water supply watershed outside WS I and the critical areas of WS II, III and IV to be developed at up to 70% impervious area. Creation of an exception to an environmental rule for two named local governments may be inconsistent with a provision in the N.C. Constitution prohibiting “local acts” related to public health.  In any case, the provision creates a special advantage for two named local governments that was not based on any evaluation of the impact on drinking water quality. (See: House Bill 600, Sec. 5)

WASTEWATER DISCHARGE 

Discharge of domestic wastewater to low and no flow streams. Amends G.S. 143-215.1 to add a  new subsection (c8) allowing discharge of domestic wastewater to low or no flow streams. “Domestic wastewater” generally refers to wastewater from plumbing fixtures in residences and other buildings; it includes human waste and wastewater from kitchens, baths and  laundry facilities. “Domestic wastewater” does not include wastewater from industrial processes.  G.S. 143-215.1 (c8)  will allow discharge of domestic wastewater that meets specific water quality standards set out in that subpart of the law. Those standards  are very tight with respect to conventional pollutants (such as fecal bacteria and nitrates), but the law does not address all potential pollutants.  For example, there are no standards for toxic pollutants and the law prohibits state permit writers from imposing additional conditions to address pollutants not addressed in the provision.  (See: House Bill 259,  Sec. 12.9)

WATER QUALITY CERTIFICATION 

Issuance of water quality certifications for dredging and energy projects. Under Section 401 of the Clean Water Act, an applicant for a federal permit must provide a certification from the state that the permitted project will be consistent with state water quality standards. The provision puts new restrictions on state issuance of Section 401 Water Quality Certifications for state-funded maintenance dredging projects  and projects involving distribution or transmission of energy or fuel (including natural gas, diesel, petroleum, or electricity):

  • DEQ must determine completeness of the Section 401 application within 30 days.
  • A decision to issue or deny the certification must be made within 60 days if no public    hearing is required or within 90 days if there is a hearing.
  • Conditions on the Section 401 certification are limited to those necessary to ensure that proposed discharges of pollutants will comply with state water quality requirements

STUDY WATER QUALITY STANDARDS.  

Narrative water quality standard.  Some background — State water quality rules set specific numerical water quality standards for many pollutants. But since new pollutants of concern emerge over time, the rules also include  a “narrative standard” for toxic pollutants that do not yet have a numerical standard in rules. The “narrative standard” provides specific technical guidance to permitting staff on how to calculate a numerical standard for the pollutant.  Most recently, DEQ has used the narrative standard rule, 15A NCAC 2B.0218,  to calculate a water quality standard for 1,4 dioxane which (as noted above) is a likely human carcinogen. The numerical value derived from the rule then becomes the reference point for limiting discharges of the pollutant to surface waters. The narrative standard provides a predictable, scientifically based method for setting a water quality standard for an emerging pollutant until a numerical standard can be incorporated into the rules — a process that can take several years.

A provision in the Regulatory Reform Act of 2023 requires the EMC to study  narrative water quality standards and report to the legislature by June 1, 2024. The study will include review of the methods for setting a water quality standard under the rule; narrative standards adopted by other states;  and U.S. EPA requirements for adoption of narrative standards. The EMC is to report its findings, including any recommendations for legislative action, to the Joint Legislative Commission on Governmental Operations. (House Bill 600, Sec. 8). The study likely responds to legal action by several local governments challenging use and enforcement of the narrative standard to limit discharges of 1,4 dioxane.

DREDGING MORATORIA

Restriction on dredging moratoria. The legislature amended G.S. 113-229 (the State Dredge and Fill Act) to add a new subsection limiting the ability of state agencies to suspend authorization for dredging in state waters to protect aquatic resources. Dredging moratoria are often seasonal, corresponding to fish spawning activity.  The new provision limits dredging moratoria unless the restriction on dredging activity is required under the Clean Water Act, Endangered Species Act, or other applicable federal law. (House Bill 600, Sec. 10.5)

DEQ’s  Division of Coastal Management issues the permits required under the State Dredge and Fill Act, but the permits also involve review by other environmental and natural resource agencies  including the state water quality program. Most dredging moratoria enforced in N.C. have been adopted under state law authority to protect fisheries habitat and particularly primary nursery areas. It is not clear whether all of the existing  state moratoria on dredging are required by federal laws and rules.

This is another instance of the General Assembly deciding that North Carolina has no need or interest in protecting state natural resources apart from meeting requirements of federal law.

Wetlands

Limit state water quality protection of wetlands. A provision in Senate Bill 582 directs the EMC to define “wetlands” for purposes of state water quality regulations to include only wetlands within the federal permitting jurisdiction of U.S. EPA and the U.S. Army Corps of Engineers under the Clean Water Act. The effect of the provision is to limit all state water quality protections to wetlands with a surface connection to rivers, lakes and streams that are “waters of the U.S.”  The definition change affects state rules that set water quality standards limiting discharge of pollutants to wetlands as well as rules permitting placement of fill material in wetlands.

Limiting state wetlands protection to wetlands in federal Clean Water Act jurisdiction will exclude wetlands that have a groundwater rather than surface connection to  water bodies. It may also exclude wetlands separated from surface waters by a manmade structure and those with a seasonal rather than consistent surface connections. The full extent of the impact on state wetlands will depend on interpretation of the recent U.S. Supreme Court decision in Sackett v. U.S. EPA which significantly restricted federal wetlands jurisdiction. The N.C. Attorney General’s Office has advised the EMC and DEQ that the new state law provision has the effect of voiding state legislation enacted in 2015 that authorized state permitting requirements for basin wetlands and bogs. (See: Senate Bill 582, Sec. 15). Much more detail on the state wetlands provision can be found in earlier posts here and here.
