Purpose of the Proposal and Its Anticipated Effects, Including Any Changes in Existing Rules: Aquatic life toxics criteria: We are proposing revisions to aquatic life toxics criteria to provide additional water quality protection for organisms that live in water.

We reviewed all of Washington's current aquatic life toxics criteria to ensure they are consistent with nationally recommended water quality criteria issued by the Environmental Protection Agency (EPA). This process included an evaluation of pollutant protection levels for endangered species and their populations in Washington waters since this rule update will require Endangered Species Act (ESA) review.

We evaluated current scientific data, methods, and modeling tools to update protection levels necessary for aquatic life in Washington's surface waters. We have also added new toxic substances into the water quality standards that EPA has recommended or that the state of Washington designates as high priority for the protection of aquatic life.

The lists below show existing criteria that we updated, and new criteria we are proposing that are not currently included in Washington's water quality standards for aquatic life toxics.

Minor nonsubstantive edits: We are adding a footnote in the surface water quality standards that cite the federal regulations for EPA promulgated human health criteria where they are the applicable criteria for CWA programs in Washington.

Reasons Supporting Proposal: A. History of Aquatic Life Toxics Criteria: We submitted freshwater and marine aquatic life criteria for 26 toxic chemicals in 1988, and EPA approved these criteria in 1988. EPA determined that additional aquatic life criteria were needed to comply with CWA Section 303 (c)(2)(B) and promulgated aquatic life criteria for Washington in the 1992 National Toxics Rule for acute and chronic freshwater and marine arsenic and selenium criteria, chronic marine copper criteria, and chronic marine cyanide criteria. Following EPA's promulgation of the 1992 National Toxics Rule, we submitted updates to toxic chemicals in 1993, 1998, and 2007, leading to Washington's withdraw from the National Toxics Rule for aquatic life toxics criteria. Washington's last update to aquatic life criteria for toxic chemicals was in 2007.

The majority of Washington's aquatic life toxics criteria have not been updated since 1992 or prior. Since the National Toxics Rule of 1992, EPA has added additional toxic substances to their list of recommended criteria and provided several updates to previously established criteria. In this rule making, we evaluated the current science for each of Washington's aquatic life toxic criteria and any new aquatic life criteria for toxic substances in this rule making.

B. Litigation: On December 29, 2021, the United States District Court ruled that EPA would be required to determine within 180 days if Washington's current aquatic life toxics criteria are consistent with CWA or if they need to be revised (NWEA v. EPA, 2021, Case No. C20-1362 MJP). If they are determined to be inadequate, CWA requires EPA to promulgate new regulations for Washington, unless the state adopts them in the meantime.

The settlement agreement requires EPA to evaluate 17 pollutants for consistency with CWA, including nine pollutants by June of 2023 and the last eight pollutants by June of 2026. EPA has determined that new and revised aquatic life criteria are necessary to protect against adverse aquatic life impacts related to the following nine pollutants: Acrolein, aluminum, arsenic, cadmium, copper, cyanide, mercury, nickel, and selenium. This determination is made in accordance with a court order directing EPA to determine whether new or revised aquatic life criteria for these nine pollutants are necessary to meet the requirements of CWA. Nw. Envtl. Advocates v. EPA, No. 2:20-cv-1362-MJP, Dkt. 84 (W.D. Wash.).

C. Triennial Review: During the last public review of ecology's draft water quality standards workplan in 2021, known as the triennial review, we received overwhelming support from commenters for updating rules for aquatic life toxics criteria based on new information and approaches to aquatic life protection. We considered and received feedback on several approaches to rule making. The different approaches to revising the aquatic life toxics criteria include:

We received public support for updates to aquatic life toxics in a single rule making and a strategy that involves two rule makings based on different chemical classes.

D. Approach to this Rule Making: We have decided to proceed with updating all necessary aquatic life toxics criteria in a single rule making. This decision is influenced in part by ongoing litigation for EPA to evaluate and potentially promulgate aquatic life toxics criteria. We anticipate that a single rule making of all aquatic life toxics criteria will be more efficient than multiple rule makings. Stakeholders, tribes, and other interested parties will be able to engage in the full scope of aquatic life toxic criteria considerations within one rule making, without ecology placing one toxic substance or group of substances at a higher priority than others.

In this rule making, we compared EPA's nationally recommended aquatic life toxics criteria against Washington's current criteria to determine if updates are needed. We also considered draft EPA criteria that were finalized before the rule proposal phase of this rule making. Furthermore, we evaluated previous ESA consultations and associated National Marine Fisheries Service (NMFS) and United States Fish and Wildlife Service (USFWS) biological opinions from other Pacific Northwest states (such as Idaho and Oregon) to anticipate whether EPA national recommendations will meet ESA protection requirements.

Previous ESA consultation reports for criteria in other states have indicated that EPA's recommendations for some aquatic life toxics may not adequately protect ESA listed species. If particular toxics are not deemed "approvable" through ESA consultation, we evaluated new scientific data, alternative methods to calculate criteria, and the new modeling tools as remedies to providing full protection to aquatic life species, including endangered species and their populations.

E. Rule-Making Scope: We have identified several aquatic life toxics criteria that we reviewed based on EPA's updates to nationally recommended criteria. For several toxic substances, EPA recommended 304(a) criteria are more stringent than ecology's aquatic life toxics criteria or have yet to be incorporated into Washington's surface water quality standards. We evaluated EPA recommendations using information from ESA consultation. If no endangered species protection concerns were present, then we proposed EPA recommendations. For those toxics with endangered species protection concerns, we proposed state-specific criteria.

In some cases, we updated criteria regardless of EPA recommendations based on new data and/or the need to adopt more protective values for endangered species and their populations.

Other background information and issues related to this rule making: Updating the aquatic life toxics criteria is a high priority for ecology. Updating the aquatic life toxics criteria was included in the five-year work plan developed as part of the 2010 triennial review. More recently, updates to aquatic life toxics criteria were outlined in our performance partnership agreement (PPA) with EPA in 2021 and in our most recent triennial review submitted to EPA in April 2022.

Since the 2010 triennial review, we have focused our toxics expertise on updating human health criteria. The decision to prioritize human health criteria updates ahead of aquatic life toxics criteria was made, in part, because of significant delays in the several ESA consultations for EPA's nationally recommended aquatic life toxics criteria. We decided it was in the state's best interest to wait for the outcomes of ESA consultations and subsequent EPA determinations of adjacent state aquatic life toxics criteria before investing resources to update our aquatic life toxics criteria.

EPA Region 10 states have submitted updates to their aquatic life toxics criteria over the past few decades, but EPA's required ESA consultations with the National Oceanographic and Atmospheric Administration, National Marine Fisheries Service (NMFS), and the United States Fish and Wildlife Service (USFWS) have been significantly delayed for several states (e.g., Oregon and Idaho). EPA consideration of Oregon's aquatic life toxics criteria adopted in 2004 was significantly delayed as the federal agencies worked through ESA Section 7 consultation. In 2013, EPA disapproved a number of aquatic life criteria that the Oregon Environmental Quality Commission (ODEQ) adopted in 2004. Since 2013, ODEQ adopted, and EPA approved, revisions to several of the disapproved criteria. EPA's approvals of Idaho's aquatic life criteria likewise have been stalled, leaving the state-adopted criteria unusable for CWA actions.

In the 2010 triennial review, ecology decided it would be most beneficial for our state to wait until final ESA consultations and subsequent EPA approvals had been completed for the adjacent states before moving forward with adopting aquatic life toxics criteria in order to increase the likelihood they would meet ESA considerations and be approved by EPA. Given the probability of a delay in federal approval, ecology decided to move forward with developing human health toxics criteria as a higher priority, to be followed by aquatic life toxics criteria when there was more certainty that EPA-recommended criteria would make it through ESA consultation.

Statutory Authority for Adoption: RCW 90.48.035 provides clear and direct authority to ecology to revise the surface water quality standards (SWQS). Additionally, 40 C.F.R. 131.20 requires states and tribes with CWA authority to periodically review and update SWQS.

This rule proposal, or portions of the proposal, is exempt from requirements of the Regulatory Fairness Act because the proposal:

Is exempt under RCW 19.85.025(3) as the rules are adopting or incorporating by reference without material change federal statutes or regulations, Washington state statutes, rules of other Washington state agencies, shoreline master programs other than those programs governing shorelines of statewide significance, or, as referenced by Washington state law, national consensus codes that generally establish industry standards, if the material adopted or incorporated regulates the same subject matter and conduct as the adopting or incorporating rule; and rules only correct typographical errors, make address or name changes, or clarify language of a rule without changing its effect.

Scope of exemption for rule proposal:

Is partially exempt:

Explanation of partial exemptions: Ecology baselines are typically complex, consisting of multiple requirements fully or partially specified by existing rules, statutes, or federal laws. Where the proposed rule differs from this baseline of existing requirements, it is typically subject to (i.e., not exempt from) analysis required under the Regulatory Fairness Act (RFA), chapter 19.85 RCW), based on meeting criteria referenced in RCW 19.85.025(3) as defined by the Administrative Procedure Act in RCW 34.05.310. The small business economic impact statement (SBEIS) below includes a summary of the baseline for this rule making, and whether or how the proposed rule differs from the baseline.

The proposed rule does impose more-than-minor costs on businesses.

SBEIS

This SBEIS presents the:

A small business is defined by RFA as having 50 or fewer employees. Estimated costs are determined as compared to the existing regulatory environment, the regulations in the absence of the rule. The SBEIS only considers costs to "businesses in an industry" in Washington state. This means that impacts, for this document, are not evaluated for government agencies.

The existing regulatory environment is called the "baseline" in this document. It includes only existing laws and rules at federal and state levels.

This information is excerpted from ecology's complete set of regulatory analyses for this rule making. For complete discussion of the likely costs, benefits, minimum compliance burden, and relative burden on small businesses, see the associated regulatory analyses document (Ecology publication no. 24-10-008, February 2024).

COMPLIANCE REQUIREMENTS OF THE PROPOSED RULE, INCLUDING PROFESSIONAL SERVICES: The baseline for our analyses generally consists of existing laws and rules. This is what allows us to make a consistent comparison between the state of the world with and without the proposed rule amendments. Should ecology not adopt the proposed rule making, standards for aquatic life criteria and their administration are determined as described within the remainder of this chapter.

State Criteria: As listed in WAC 173-201A-240, Table 240 and relevant footnotes.

National EPA Recommended Water Quality Criteria: EPA periodically updates their recommended water quality criteria based on new information for each toxic chemical. Aquatic life criteria for toxic chemicals are considered by the EPA to be the highest concentration of specific pollutants or parameters in water that are not expected to pose a significant risk to the majority of species in a given environment or a narrative description of the desired conditions of a water body being "free from" certain negative conditions. Not moving forward with this rule making would subject ecology to EPA's promulgation of their federal criteria.

Clean Water Act: Section 303 (c)(2)(A).

Water Pollution Control Act: RCW 90.48.010 and 90.48.035.

Permitting Guidelines: Permitting guidelines help permit writers determine how to approach different permit scenarios. They assist permit writers in how to think through meeting water quality criteria for protection of aquatic life to permittee-specific requirements. While not a legal requirement, guidance informs how aquatic life criteria might impact permittees who discharge effluent to water bodies. Therefore, in describing the baseline for this analysis of the rule amendments, it is necessary to consider the permitting guidelines in the baseline and amended scenarios, as they will contribute to the cost and benefit estimates and discussion of impacts.

Ecology uses the Water Quality Program Permit Writer's Manual (Ecology, 2018) for technical guidance when developing wastewater discharge permits. A general overview of the permitting process for all dischargers includes:

To evaluate the effect of effluent toxic pollutants on a receiving water, the permit writer uses the water quality criteria and standards, the criteria for mixing zones, and an analysis of the concentrations of specific pollutants or effects of pollutants within or at the edge of the mixing zone or the assigned dilution factor. The requirement for imposing effluent limitations for the protection of water quality does not require a demonstration of impact beyond any doubt but only that there is a determination of reasonable potential determined by a rational and scientific process.

Defining water quality impacts and developing effluent limits is usually more complex for toxic pollutants than for the other pollutants. The aquatic life toxic criteria are given at two levels (acute and chronic), each of which contains three components (magnitude, duration, and frequency). The analysis to predict water quality impacts and thus to define effluent limits must be conducted for both acute and chronic criteria to define the most limiting criteria. Many of the criteria for toxic pollutants depend on variable receiving water conditions. Permit writers calculate effluent limits to protect receiving water quality during critical (worst-case) conditions.

Impaired Waterbody Listing and Cleanup Plan: The CWA's section 303(d) established a process to identify and clean up polluted waters. Every two years, all states are required to perform a water quality assessment of surface waters in the state, including all the rivers, lakes, and marine waters where data are available. Ecology compiles its own water quality data and federal data and invites other groups to submit water quality data they have collected. All data submitted must be collected using appropriate scientific methods. The assessed waters are placed in categories that describe the status of water quality. Once the assessment is complete, the public is given a chance to review it and give comments. The final assessment is formally submitted to the EPA for approval.

Waters with beneficial uses, such as for drinking, recreation, aquatic habitat, and industrial use, that are impaired by pollutants are placed in the polluted water category in the water quality assessment 303(d) list. These water bodies fall short of state surface water quality standards and are not expected to improve within the next two years. The 303(d) list, so called because the processes for developing the list and addressing the polluted waters on the list are described in section 303(d) of the federal CWA, comprises waters in the polluted water category.

Ecology's assessment of which waters to place on the 303(d) list is guided by federal laws, state water quality standards, and the policy on the Washington State Water Quality Assessment (WQP Policy 1-11; March 2023). This policy describes how the standards are applied, requirements for the data used, and how to prioritize total maximum daily loads (TMDL), among other issues. In addition, even before a TMDL is completed, the inclusion of a water body on the 303(d) list can reduce the amount of pollutants allowed to be released under permits issued by ecology.

Waters placed on the 303(d) list require the preparation of a water cleanup plan (TMDL) or other approved water quality improvement project. The improvement plan identifies how much pollution needs to be reduced or eliminated to achieve clean water and allocates that amount of required pollution reduction among the existing sources.

Past or Existing Compliance Behavior: The baseline includes past or existing compliance behavior. This includes behavior undertaken in response to federal and state laws, rules, permits, guidance, and policies. This also includes business decisions in response to regulatory, economic, or environmental changes. Such behavior might include, but is not limited to, existing treatment technologies, production processes, and effluent volumes. Including these behaviors in the baseline is necessary to assess the incremental impacts of the proposed rule over existing requirements.

Discharger and TMDL Growth Trajectories: The amended rule applies to existing and future dischargers, on existing and future impaired water bodies, and water bodies with TMDLs and without TMDLs, so the baseline must also account for attributes and behaviors of future dischargers and future TMDLs.

The baseline forecast of future growth in the number, locations, and types of TMDLs is based on past TMDL behavior and planned structuring of TMDL planning. We forecast expected types of TMDLs based on prospective new locations, and how they fit into the framework for planning and completing TMDLs.

The baseline forecast of future dischargers is based on attributes of existing dischargers. The forecast assumes that future discharger contaminants and concentrations are the same as in existing dischargers. This means unexpected changes in technology over time (e.g., using different inputs or technologies) that reduce pollutants in effluent would reduce the actual impacts of the proposed rule.

Existing Allowance for Compliance Schedules: The baseline includes existing compliance schedules. A compliance schedule is an enforceable tool used as part of a permit, order, or directive to achieve compliance with applicable effluent standards and limitations, water quality standards, or other legally applicable requirements. Compliance schedules include a sequence of interim requirements such as actions, operations, or milestone events to achieve the stated goals. Compliance schedules are a broadly used tool for achieving compliance with state and federal regulations; compliance schedules under CWA are defined federally at CWA 502(17) and 40 C.F.R. Section 122.2.

Proposed rule amendments: The proposed rule amendments would amend WAC 173-201A-240 Toxic substances, specifically aquatic life criteria including, but not limited to, Table 240 and footnotes.

Note that since the EPA criteria recommendations are in this rule making's baseline, the analytical scope of this regulatory analysis is reduced to new or existing aquatic life criteria that: (1) Differ from WAC 173-201A-240 (Table 240); and (2) differ from EPA guidance or EPA derivation methods (due to ESA concerns, new science, and/or having no EPA recommendation). Applying this filter (see Table 16 in Appendix B for illustration and additional information), this analysis includes the following:

COSTS OF COMPLIANCE: EQUIPMENT, SUPPLIES, LABOR, AND PROFESSIONAL SERVICES: Costs would originate from permit holders (in most cases, facilities) that change behavior to comply with new or revised permit conditions based on the proposed rule. However, many permit holders do not process the materials or operate equipment that would lead to any change in permit limits based on the new criteria, or already report effluent numbers low enough to comply with the proposed rule. Therefore, costs are not created by all permits and all criteria.

Estimated costs are generated by potential increases in level 1, 2, and 3 exceedances and the corrective actions required by them for existing criteria (with copper and zinc accounting for all of the level 2 and 3 exceedances), and increased monitoring and lab costs for new criteria. For additional context, level 1 violation would lead to the equivalent of minor adjustments like sweeping and moving materials away from drains to come into compliance (labor costs). Level 2 violation might lead to installing berms, removing materials suspected of contributing to pollutants, and coating various pipes and surfaces (equipment, supply, and labor costs). At a minimum, a level 2 violation would necessitate development and implementation of a source control plan. Level 3 violation requires facility improvements likely to include water treatment filters, catch basins, and other engineering solutions (equipment, supply, labor, and professional services costs). Due to project complexity and data availability, compliance costs below reflect combined labor, professional services, and supplies where applicable.

Estimated Present Value of Total Cost

COMPARISON OF COMPLIANCE COST FOR SMALL VERSUS LARGE BUSINESSES: We calculated the estimated per-business costs to comply with the proposed rule amendments, based on the costs estimated in Chapter 3 of this document. In this section, we estimate compliance costs per employee.

The average affected small business likely to be covered by the proposed rule amendments employs about 20 people. The largest 10 percent of affected businesses employ an average of 4,638 people. These estimates were generating by cross referencing permit addresses with Dun and Bradstreet data on global employment.1 Based on cost estimates in Chapter 3, we estimated the following compliance costs per employee.

Compliance Costs per Employee

We conclude that the proposed rule amendments are likely to have disproportionate impacts on small businesses and, therefore, ecology must include elements in the proposed rule amendments to mitigate this disproportion as far as is legal and feasible.

MITIGATION OF DISPROPORTIONATE IMPACT: RFA (RCW 19.85.030(2)) states that: "Based upon the extent of disproportionate impact on small business identified in the statement prepared under RCW 19.85.040, the agency shall, where legal and feasible in meeting the stated objectives of the statutes upon which the rule is based, reduce the costs imposed by the rule on small businesses. The agency must consider, without limitation, each of the following methods of reducing the impact of the proposed rule on small businesses:

(a) Reducing, modifying, or eliminating substantive regulatory requirements;

(b) Simplifying, reducing, or eliminating recordkeeping and reporting requirements;

(c) Reducing the frequency of inspections;

(d) Delaying compliance timetables;

(e) Reducing or modifying fine schedules for noncompliance; or

(f) Any other mitigation techniques including those suggested by small businesses or small business advocates."

We considered all of the above options, the goals and objectives of the authorizing statutes (see Chapter 6), and the scope of this rule making. We limited compliance cost-reduction methods to those that:

Modifying regulatory requirements, changing reporting requirements, reducing the frequency of inspections, delaying compliance timetables, or modifying fine schedules would not meet statutory objectives or are not feasible and within the scope of this rule making. This rule making was initiated specifically to amend WAC 173-201A-240 aquatic life toxics criteria (and make necessary supporting changes), while not amending other aspects of requirements and implementation of broader surface water quality standards.

It was not feasible in the proposed rule amendments to directly mitigate disproportionate impacts to small businesses, however, multiple elements of the baseline rule already in place serve to mitigate compliance costs for small businesses:

WAC 173-224-090 may reduce fees for all small businesses holding or applying for a state waste discharge or NPDES permit issued by ecology.

WAC 173-224-090 allows small businesses to receive a fee reduction of 50 percent, but not less than the minimum permit fee of $150, if they are determined to be eligible under the following criteria:

(1) Be a corporation, partnership, sole proprietorship, or other legal entity formed for the purpose of making a profit;

(2) Be independently owned and operated from all other businesses (i.e., not a subsidiary of a parent company);

(3) Have annual sales of $1,000,000 or less of the goods or services produced using the processes regulated by the waste discharge or individual stormwater discharge permit (we identified 605 small business permittees in Washington that meet this definition); and

(4) Have an original annual permit fee assessment totaling $500 or greater.

In addition to the small business fee reduction, any small business with annual gross revenue totaling $100,000 or less from goods and services produced using the processes regulated by the discharge permit may apply for an extreme hardship fee reduction. If the permit holder is determined eligible, the annual permit fee is reduced to the minimum annual permit fee of $150.

SMALL BUSINESS AND LOCAL GOVERNMENT CONSULTATION: We involved small businesses, local governments, and tribes in its development of the proposed rule amendments, using: Public webinars in October 2022, April 2023, and October 2023; and tribal webinars in April 2023 and October 2023.

NORTH AMERICAN INDUSTRY CLASSIFICATION SYSTEM (NAICS) CODES OF INDUSTRIES IMPACTED BY THE PROPOSED RULE: Businesses that hold permits potentially affected by the proposed rule fall within the following industry categories. Note that associated NAICS codes and definitions are discussed further at https://www.census.gov/naics/.

Industries and Their Associated NAICS Codes that are

Impacted by the Rule

CONSIDERATION OF LOST SALES OR REVENUE, IMPACT ON JOBS: Businesses that would incur costs could experience reduced sales or revenues if the proposed rule amendments significantly affect the prices of the goods they sell. The degree to which this could happen is strongly related to each business's production and pricing model (whether additional lump-sum costs would significantly affect marginal costs), as well as the specific attributes of the markets in which they sell goods, including the degree of influence each firm has on market prices, as well as the relative responsiveness of market demand to price changes. Finally, overall shifts in economic activity in the state, including competition within markets and attributes of the labor market simultaneously adjust in response to changes in compliance costs. Similarly, employment within directly impacted industries, other industries in Washington, the labor market within and outside of the state, and in the state as a whole would also adjust in response to a change in costs.

We used the REMI E3+ model for Washington state to estimate the impact of the proposed rule amendments on directly affected markets, accounting for dynamic adjustments throughout the economy. The model accounts for variables including but not limited to: Interindustry impacts; price, wage, interstate and international trade, and population or labor market changes; and dynamic adjustment of all economic variables over time.

The results of the REMI E3+ model shows that the rule would impact a variety of industries, costing the Washington economy an estimated range between $23 million to $69 million in annual output at its peak (total amount of goods and services produced by Washington businesses) across all sectors. For reference, in the first quarter of 2023, Washington state's annual gross domestic product (GDP) was estimated at $761 billion. In percentage terms, this impact amounts to .003 percent and .009 percent of GDP for low and high estimates, respectively.

Output losses are projected to begin in 2025 following the proposed rule implementation and increase as permits become renewed. These amount to a loss of roughly $1 million in the low- and high-cost scenario in the first year of the rule and increase to $23 million and $69 million for the low- and high-cost scenarios, respectively by 2030. Output losses slowly decrease after 2030, and by 2045 the output loss is projected to have declined under the low- and high-cost scenarios to $1 million and $2 million, respectively.

Retail trade, and construction is impacted the most among all industries, accounting for 13 percent each of the total output loss in high and low scenarios, followed by wholesale trade, real estate, and state and local government. Note that it is not unusual for the construction and retail industries to have high projected impacts from a rule as they are often quite sensitive to any changes to the market in REMI models. The rule also impacts a breadth of affected industries, many of which indirectly support retail and construction activities.

Modeled Economic Impacts to Output

The proposed rule would result in transfers of money within and between industries, as compared to the baseline. The modeled impacts on employment are the result of these transfers and the way in which REMI projects these transfers to be utilized within the broader economy, as well as changes to prices and other economic variables across all industries in the state. REMI results project an immediate state-wide loss of one full-time equivalent positions (FTEs) under the low-cost scenario and four in the high-cost scenario in the year 2025. This loss increases over the next two years, peaking in 2030 with a projected loss of 113 and 337 FTEs, under the low- and high-cost scenarios, respectively. The statewide loss in FTEs is lessened after 2030 such that in 2045 the statewide projected loss is reduced to two FTEs in the low-cost scenario, and six FTEs in the high-cost scenario in 2045.

Industries that are most impacted are listed below. The construction sector is projected to be the most heavily impacted industry, accounting for about 17 percent of the FTE loss from this rule statewide in 2030. Closely related to sensitivities in economic output discussed above, it is not unusual for the construction industry to have high projected job impacts from a rule as the construction industry is often quite sensitive to any changes in the market in REMI models. The next four sectors most heavily impacted in terms of projected job loss are retail trade, state and local government, wholesale trade, and real estate. While some of these sectors may not be as directly impacted from the rule making as others, note that the REMI model is sensitive to reductions in population growth compared to baseline, potentially leading to lower demand for retail goods, public services, and housing.
