§§ 1-12 — MOTOR VEHICLE PROPERTY TAX ASSESSMENT S 
Changes various laws on motor vehicle assessment and property tax billing procedures set 
to take effect on October 1, 2024, including (1) adjusting the depreciation schedule 
assessors must use to value motor vehicles, (2) eliminating a requirement that OPM 
define a class of motor vehicles to be treated as personal property for taxing purposes, (3) 
specifying how assessors must value commercial vehicle modifications and attachments, 
and (4) eliminating certain statutory deadlines for supplemental motor vehicle tax bills 
The bill changes laws on motor vehicle assessments and property tax 
billing procedures that, by law, take effect October 1, 2024 (see 
Background — Changes to Motor Vehicle Assessment Laws in 2023 and 2024). 
Principally, the bill does the following: 
1. adjusts the depreciation schedule, increasing the taxable portion 
of each vehicle’s manufacturer’s suggested retail price (MSRP) by 
five percentage points and making corresponding changes to the 
increments over the 20-year depreciation schedule (§ 3); 
2. eliminates a requirement that the Office of Policy and 
Management (OPM) define a class of motor vehicles that would 
be treated as non-vehicle personal property for certain property 
tax purposes (§§ 1-2, 4-5 & 7);   2024SB-00501-R00SS1-BA.DOCX 
 
Researcher: RP 	Page 3 	6/26/24 
 
3. requires assessors to determine whether to value modifications 
and attachments to commercial vehicles, as well as the vehicles 
to which they are affixed, as motor vehicles or as non-vehicle 
personal property (§§ 3 & 4);  
4. restores a provision in the underlying law specifying that 
registered motor vehicles are not to be listed on a personal 
property declaration (§ 4); and 
5. eliminates certain statutory deadlines for supplemental motor 
vehicle tax bills and re-establishes prior law’s time limit for 
taxpayers to apply for certain credits (e.g., for stolen or totaled 
vehicles) (§§ 8-10). 
With respect to how vehicles are assessed, the bill additionally: 
1. requires OPM to annually establish valuation guidelines, in 
consultation with the Department of Motor Vehicles (DMV), that 
assessors must use to determine vehicles’ use for property tax 
purposes (§ 2), and 
2. requires assessors to value tax-exempt commercial trucks, truck 
tractors, and tractors and semitrailers used exclusively to 
transport freight for hire in the same way as other vehicles (i.e., 
using their MSRP subject to depreciation or assessor-determined 
values, as applicable), rather than using their purchase cost 
subject to depreciation (§ 10). 
The bill also explicitly authorizes taxpayers to contest the MSRP used 
to assess their vehicles in the same way existing law sets for appeals of 
the current valuation method (i.e., at the next board of assessment 
appeals meeting after the tax bill becomes due and then to the Superior 
Court) (§§ 3 & 8). It also makes numerous minor and conforming 
changes. 
EFFECTIVE DATE: July 1, 2024, and applicable to assessment years 
starting on or after October 1, 2024, except for a conforming change in § 
11, which is effective July 1, 2024, and a technical correction in § 12,  2024SB-00501-R00SS1-BA.DOCX 
 
Researcher: RP 	Page 4 	6/26/24 
 
which is effective upon passage. 
Depreciation Schedule (§ 3) 
Beginning October 1, 2024, current law requires vehicles to be valued 
for property tax purposes as a percentage of their MSRP, based on a 20-
year depreciation schedule. The bill increases the taxable portion of 
vehicles’ MSRP by five percentage points, as shown in the table below. 
Additionally, under the bill, vehicles that are at least 20 years old must 
be assessed, rather than valued, at no less than $500.

Commercial Vehicle Modifications and Attachments (§§ 3 & 4) 
Beginning October 1, 2024, the bill requires assessors to determine 
whether to value commercial motor vehicles with modifications or 
certain attachments (i.e., those designed, manufactured, or modified to 
be affixed to the vehicle) as motor vehicles or as personal property. It 
requires assessors to do the same for the modifications and attachments. 
(By law, motor vehicles and other, non-vehicle personal property are 
valued differently (e.g., using different methods and depreciation 
schedules).) Under the bill, the assessor must determine the valuation of 
any modifications or attachments to these vehicles based on whether  2024SB-00501-R00SS1-BA.DOCX 
 
Researcher: RP 	Page 5 	6/26/24 
 
they are intended to be permanently affixed to the vehicle. 
Under the bill, non-permanent modifications and attachments are 
considered personal property, which taxpayers must list on their annual 
personal property declarations. (Presumably, attachments and 
modifications that are intended to be permanently affixed are valued as 
part of the motor vehicle, not as personal property.) 
Personal Property Declarations (§ 4) 
Under current law, starting by October 1, 2024, OPM must annually 
define a schedule of motor vehicle plate classes to be treated as non-
vehicle personal property and taxpayers must list those vehicles on a 
personal property declaration. In addition to eliminating the OPM-
established schedule of plate classes, the bill restores a provision in the 
underlying law specifying that registered motor vehicles are not to be 
listed on a personal property declaration. (However, as described above, 
the bill also requires the assessor to determine whether to value a 
commercial motor vehicle with modifications or attachments as 
personal property listed on a personal property declaration.)  
Supplemental Motor Vehicle Tax Bills and Credits (§§ 8-10) 
Late Additions to the Grand List. Under current law, when an 
assessor receives notice from the DMV commissioner about a taxable 
vehicle that is not already on the town’s taxable grand list, he or she 
must assess the vehicle and add it to the town’s grand list for the 
immediately preceding October 1. Under the bill, beginning October 1, 
2024, the assessor must instead add the vehicle to the town’s taxable 
grand list. (It is unclear to which grand list this refers.) 
Supplemental Tax Bill Due Dates. By law, until October 1, 2024, tax 
bills for vehicles (including replacement vehicles and temporarily 
registered commercial vehicles) registered after the start of the 
assessment year (October 1) are due the following January 1 in a 
supplemental tax bill, and interest on delinquent payments begins 
accruing February 1. Starting October 1, 2024, current law creates a 
second supplemental tax bill due date (July 1) and, in doing so, generally 
advances the payment date for vehicles registered after October 1 but  2024SB-00501-R00SS1-BA.DOCX 
 
Researcher: RP 	Page 6 	6/26/24 
 
before April 1.  
The bill eliminates these statutory due dates and instead makes 
supplemental bills payable not later than the first day of the month after 
they become due. (Presumably, this means municipalities will set 
supplemental tax bills’ due dates and interest will begin accruing the 
first day of the next month.) 
Where Supplemental Motor Vehicle Tax Is Paid. Under current 
law, supplemental motor vehicle tax bills for vehicles registered after 
the start of the assessment year (other than replacement vehicles) are 
due to the municipality in which the vehicle was last registered in the 
assessment year immediately preceding the day on which the tax is 
payable. The bill instead makes these supplemental tax bills due to the 
municipality where the vehicle was first registered during the 
assessment year. (By law, unchanged by the bill, supplemental motor 
vehicle tax bills are prorated for the number of months left in the 
assessment year.)  
By law, and under the bill, supplemental tax bills on replacement 
vehicles are due to the municipality that billed the original, replaced 
vehicle.  
Deadline to Request Credit. The bill reestablishes prior law’s 
deadline for a taxpayer to claim a credit against their property taxes for 
a vehicle that was sold, totaled, stolen, or registered by the taxpayer in 
another state upon moving. So, under the bill, the deadline remains the 
December 31 following the first full assessment year after the 
assessment year in which the event (e.g., sale or theft) occurred. 
Background — Changes to Motor Vehicle Assessment Laws in 
2023 and 2024 
PA 22-118, §§ 497-509, beginning October 1, 2023, (1) required 
assessors to value vehicles using their MSRPs, subject to depreciation 
(rather than using a guide OPM annually selects); (2) required DMV to 
give municipalities a supplemental list of vehicles it registered on a 
monthly, rather than annual, basis; and (3) modified the timeline for 
supplemental bills. However, PA 23-304, §§ 209-219, delayed these  2024SB-00501-R00SS1-BA.DOCX 
 
Researcher: RP 	Page 7 	6/26/24 
 
changes by one year, until the 2024 assessment year.  
§ 13 — MOTOR VEHICLE MILL RATE  
Requires municipalities and districts that impose a motor vehicle mill rate that differs 
from the mill rate for other taxable property to impose the lower rate on motor vehicles; 
explicitly authorizes them to set the motor vehicle mill rate as low as zero mills; requires 
OPM to send specified notices to municipal CEOs about the municipality’s option to 
reduce its mill rate  
Current law allows municipalities and districts to tax motor vehicles 
at a different rate than other taxable property and caps the motor vehicle 
mill rate at 32.46 mills. The bill (1) requires those that set different mill 
rates for motor vehicles and other taxable property to impose the lower 
rate on motor vehicles and (2) explicitly authorizes them to set the motor 
vehicle mill rate as low as zero mills. 
The bill also requires the OPM secretary to annually notify each 
municipality’s chief executive officer (CEO) that: 
1. the municipality has the option to reduce its motor vehicle mill 
rate to less than 32.46 mills, even as low as zero mills, and  
2. its motor vehicle mill rate may be different than its rate for other 
taxable property, so long as it is lower. 
The OPM secretary must also notify each municipal CEO, before the 
municipality implements a revaluation, that the municipality has the 
option to consider and evaluate reducing its motor vehicle mill rate in 
the same fiscal year in which it implements the revaluation. 
EFFECTIVE DATE: July 1, 2025 
§§ 14-29 — INNOVATION BANKS 
Replaces a current type of Connecticut-organized bank (“uninsured bank”) with a 
substantially similar type under a different name (“innovation bank”) 
The bill replaces all references to “uninsured banks” in the state’s 
banking laws with “innovation banks.” In doing so, it makes the 
requirements and conditions that apply to uninsured banks under 
current law apply to innovation banks instead. 
The bill defines “innovation bank” similarly to “uninsured bank”  2024SB-00501-R00SS1-BA.DOCX 
 
Researcher: RP 	Page 8 	6/26/24 
 
(i.e., a Connecticut-chartered or -organized bank and trust company, 
savings bank, or savings and loan association that does not accept retail 
deposits). However, while by definition current law does not require 
“uninsured banks” to have Federal Deposit Insurance Corporation 
(FDIC) insurance for their deposits, the bill instead expressly allows 
“innovation banks” to accept nonretail deposits that are eligible for 
FDIC insurance. 
Separate from its definition, the bill also authorizes each innovation 
bank to receive nonretail deposits (including from a corporation that 
owns the majority of the bank’s shares) and to secure deposit insurance 
for them, including from the FDIC.  
By law, “retail deposits” are deposits by anyone other than accredited 
investors as defined in federal securities regulations. Generally, 
“accredited investors” include, among other entities, certain banks, 
securities brokers or dealers, insurance companies, investment 
companies, business development companies, qualifying retirement 
and employee benefit plans, trusts with assets over $5 million, and 
people with an individual income over $200,000 in each of the past two 
years or $300,000 jointly with a spouse (17 C.F.R. § 230.501(a)). 
Lastly, the bill makes several technical and conforming changes. 
EFFECTIVE DATE: July 1, 2024  
§ 30 — INTEREST ON CERTAIN TAX UNDERPAYM ENTS 
Exempts taxpayers from paying interest on underpayments of corporation business, pass-
through entity, and personal income taxes if the underpayment was due to an amended 
return filing necessitated by IRS guidance on the federal employee retention credit 
The bill exempts taxpayers from paying interest on underpayments 
of corporation business, pass-through entity, and personal income taxes 
if the underpayment was due to an amended return filing required by 
Internal Revenue Service (IRS) guidance on the federal employee 
retention credit. It requires the Department of Revenue Services (DRS) 
to treat any interest already paid on these underpayments as an 
overpayment and refund it to taxpayers without interest.  2024SB-00501-R00SS1-BA.DOCX 
 
Researcher: RP 	Page 9 	6/26/24 
 
EFFECTIVE DATE: Upon passage 
Background — Federal Employee Retention Credit 
The federal employee retention credit is a refundable credit against 
employment taxes designed for eligible businesses that continued 
paying employees during the COVID-19 pandemic. Eligible employers 
were allowed to claim the credit on an original or amended employment 
tax return for qualified wages paid between March 13, 2020, and 
December 31, 2021. In September 2023, the IRS ordered a moratorium 
on processing new credit claims due to its concerns that a substantial 
share of new claims was fraudulent. It subsequently implemented 
stricter compliance reviews, a voluntary disclosure program that allows 
taxpayers to pay back a credit they received but were not entitled to, 
and a special withdrawal program for taxpayers with pending claims 
who realize they may have filed an inaccurate tax return. 
§ 31 — GENERAL INSURANCE ASSESSMENT 
Changes the basis for calculating the annual general assessment that domestic insurers 
and HMOs pay the Insurance Department 
By law, domestic insurers and HMOs pay an annual assessment to 
the Insurance Department to cover the expenses of the Insurance 
Department, Office of the Healthcare Advocate, and Office of Health 
Strategy, among other things.  
The bill changes the basis for calculating this annual assessment. 
Under current law, the assessment is generally calculated based on the 
amount the insurers and HMOs paid in Connecticut insurance 
premiums taxes for the prior calendar year. For certain local domestic 
insurers, it is based on the amount before applying the insurance 
premiums tax credit allowed for these insurers. The bill instead bases 
the assessment on the total amount of Connecticut insurance premiums 
taxes the insurers and HMOs reported to DRS two years prior before 
applying any allowable or available tax credits.  
The bill correspondingly requires the DRS commissioner to report 
these tax amounts in the statement he must give the insurance 
commissioner annually by June 30. It also makes related technical and  2024SB-00501-R00SS1-BA.DOCX 
 
Researcher: RP 	Page 10 	6/26/24 
 
conforming changes. 
EFFECTIVE DATE: October 1, 2025 
§§ 32 & 33 — SCHOOL CONSTRUCTION PROJECT MANAGERS 
Prohibits construction managers on school construction projects from bidding on project 
subcontracts 
The bill reinstates a provision prohibiting construction managers on 
school construction projects from bidding on elements of the project 
(i.e., subcontracts) they are managing. PA 24-151 had removed the 
prohibition and the bill repeals that provision of PA 24-151. The bill 
leaves intact other changes to school construction law made by PA 24-
151. 
EFFECTIVE DATE: July 1, 2024, except the repealer section is 
effective upon passage. 
§§ 34-42 — SOUTH CENTRAL CONNECTICUT REG IONAL WATER 
AUTHORITY (RWA) AND CREATION OF AQUARION WATER 
AUTHORITY  
Amends RWA’s charter to contemplate the acquisition of Aquarion Water Company or its 
subsidiaries, including giving RWA specific authority to borrow or bond for this purpose; 
upon such acquisition, creates a state-chartered regional water authority and generally 
gives the new Aquarion Water Authority the same powers and structure as RWA, 
including giving both authorities the same governing board 
The bill establishes provisions that, under specified circumstances, 
create a new regional water authority, Aquarion Water Authority 
(AWA), serving the Aquarion Regional Water District. The bill 
contemplates the creation of the new water authority after RWA or 
AWA acquires Aquarion Water Company or one or more of its 
subsidiaries (“the company”). (Currently, the company is a subsidiary 
of Eversource serving customers in Connecticut, Massachusetts, and 
New Hampshire.) Under existing law, unchanged by the bill, the 
company’s acquisition requires Public Utilities Regulatory Authority 
(PURA) approval. The bill makes the charter it establishes for AWA part 
of RWA’s charter. 
Identically to RWA, which the legislature chartered in 1977 to serve 
the New Haven area, the bill states that the purpose of creating AWA is  2024SB-00501-R00SS1-BA.DOCX 
 
Researcher: RP 	Page 11 	6/26/24 
 
to assure the adequate provision of water and disposal of wastewater at 
a reasonable cost in the region and to promote conservation and 
compatible recreational use of the land held by the authority. Under the 
bill, AWA is overseen by a representative policy board and governing 
board, as is the case for RWA.  
If RWA or AWA acquire the company, the bill expands RWA’s 
governing board to include members living in AWA’s jurisdiction. The 
same governing board oversees both RWA and AWA. The bill also 
makes RWA’s chief executive officer the same as AWA’s. The bill gives 
AWA nearly identical powers and responsibilities to RWA, including 
the power to purchase and condemn property, operate water supply 
and wastewater systems, and issue bonds. Like RWA, AWA is subject 
to regulation by the state departments of public health and energy and 
environmental protection, but it is not regulated by PURA.   
The bill specifies that its provisions concerning RWA and AWA 
sunset on December 31, 2027, unless PURA approves RWA’s or AWA’s 
acquisition and operation of Aquarion Water Company , or its 
subsidiaries, by that date.  
EFFECTIVE DATE: Upon passage  
Aquarion Regional Water District’s Membership  
Under the bill, the district consists of: Beacon Falls, Bethel, 
Bridgeport, Brookfield, Burlington, Canaan, Cornwall, Danbury, 
Darien, East Derby, East Granby, East Hampton, Easton, Fairfield, 
Farmington, Goshen, Granby, Greenwich, Groton, Harwinton, Kent, 
Lebanon, Litchfield, Mansfield, Marlborough, Middlebury, Monroe, 
New Canaan, New Fairfield, New Hartford, New Milford, Newtown, 
Norfolk, North Canaan, Norwalk, Norwich, Oxford, P lainville, 
Redding, Ridgefield, Salisbury, Seymour, Shelton, Sherman, Simsbury, 
Southbury, Southington, Stamford, Stonington, Stratford, Suffield, 
Torrington, Trumbull, Washington, Weston, Westport, Wilton, Wolcott, 
and Woodbury.  
If the authority does not own property or serve customers in any of  2024SB-00501-R00SS1-BA.DOCX 
 
Researcher: RP 	Page 12 	6/26/24 
 
these municipalities, then the town or city is excluded from the district. 
(This was also the case, for a period of time, in the enabling legislation 
for RWA.)  
AWA’s Representative Policy Board 
As is the case under existing law for RWA, the bill establishes a 
representative policy board for the authority, consisting of (1) an elector 
of each member municipality, appointed by the respective chief elected 
official and approved by the legislative body, and (2) one member 
appointed by the governor. The bill specifies their initial staggered 
terms; their compensation is the same as members of RWA’s policy 
board ($250 per day for each day of service, adjusted periodically for 
inflation, with the chairperson receiving 50% more than other 
members). Like RWA, the votes of the municipally-appointed members 
of the board are weighted by the number of customers and amount of 
authority-owned land in the municipality.  
Initially, RWA’s policy board serves as AWA’s, until AWA’s is 
appointed, which cannot be before PURA approves RWA’s or AWA’s 
acquisition of the company.  
Duties. Identically as for RWA, the AWA policy board must decide 
whether to approve, after a hearing, various major authority actions, 
including setting rates and charges (see below), acquiring some or all of 
another water or wastewater system, most capital projects that cost 
more than $3.5 million, and noncore business investments of more than 
$1.5 million (as for RWA, these thresholds are adjusted every three 
years). It also decides whether to approve bond issues.   
Like RWA, the board must have standing committees on land use 
and management, finance, and consumer affairs. The bill also specifies 
public notice requirements for hearings (e.g., on land sales) conducted 
by the policy board. 
Appeals. If the governing board (see below) or others are aggrieved 
by the policy board’s decision (e.g., its rates, siting plans, or sale of 
property), they have the same recourse options as those aggrieved by  2024SB-00501-R00SS1-BA.DOCX 
 
Researcher: RP 	Page 13 	6/26/24 
 
RWA’s policy board. This means, under certain circumstances, they can 
appeal the decision to Hartford superior court (in the case of RWA, 
filings are made in New Haven superior court). (Neither RWA nor 
AWA are subject to the Uniform Administrative Procedure Act.) 
AWA’s Governing Board  
Under the bill, AWA is governed by 11 individuals, five of whom are 
district residents appointed by the AWA policy board and six of whom 
are the members appointed to RWA’s governing board by RWA’s policy 
board. This governing board constitutes the authority. Board members 
receive the same compensation as policy board members if the latter 
board approves it. No one can be a member of both the policy and 
governing boards. But the bill requires the boards of AWA and RWA to 
be identical.  
Initially, when AWA’s creation is first triggered, RWA’s governing 
board serves as AWA’s, until its AWA district members are appointed. 
The first chair and vice-chair, for two-year terms, are the same as 
RWA’s, but subsequent chairs and vice-chairs are elected by the board’s 
membership, as is the case for RWA under existing law.   
(As discussed below, the bill makes conforming changes to RWA’s 
charter to align RWA’s board with AWA’s, although it appears they 
may have different chairpersons after the initial AWA chair’s term.) 
General Powers 
With limited exceptions, AWA’s powers are identical to RWA’s. 
These include the powers to: 
1. acquire real and personal property by purchase or condemnation 
(but, as with RWA, it cannot acquire property by condemnation 
to use for noncore businesses); 
2. construct, develop, and operate water supply and wastewater 
systems and set the rates and charges for these systems (see 
below); 
3. borrow money and issue bonds;  2024SB-00501-R00SS1-BA.DOCX 
 
Researcher: RP 	Page 14 	6/26/24 
 
4. acquire real property for conservation and recreational purposes 
if these uses will not harm water quality; 
5. partake in noncore business activities, such as sustainable 
manufacturing support or certain energy projects; and 
6. employ staff (subject to the laws on municipal employee 
collective bargaining) and enter into agreements with its 
employees’ representatives on participating in any applicable 
state or municipal employee retirement plan. 
As is the case for RWA, the governing board sets rates and charges, 
subject to approval by the representative policy board, and the bill 
specifies ratemaking principles. Unpaid rates and charges are a lien 
against the owner of the affected property, and these liens take 
precedence over all other liens or encumbrances except taxes.  
The bill specifically authorizes both RWA and AWA to borrow or 
bond to acquire Aquarion Water Company or any of its subsidiaries.   
Acquiring a Water System Outside the District. The bill makes it a 
“noncore business” activity for AWA to acquire Aquarion Water 
Company or its subsidiaries. (Under the bill, this is also a noncore 
business activity for RWA.) For both AWA and RWA, noncore business 
expenses exceeding $1.5 million require policy board approval. 
For RWA and AWA, noncore business activities are generally limited 
by a provision specifying that at the time of an investment in a noncore 
business, the authority’s investment, less returns of or on the 
investments, cannot exceed the greater of (1) 5% of the authority’s net 
utility plant devoted to its water and wastewater utility businesses or 
(2) a higher amount approved by the policy board. (But the bill creates 
an exception for RWA, see below.)   
Responsibilities  
As the law requires for RWA, the bill generally requires the authority, 
if it acquires a private water company operating within its district, to 
retain certain employees and provide them with similar benefits and  2024SB-00501-R00SS1-BA.DOCX 
 
Researcher: RP 	Page 15 	6/26/24 
 
seniority.  
Like RWA, AWA also must develop land use standards and 
disposition policies, subject to approval by the policy board. As the law 
does for RWA, the bill requires that the policies include standards for 
categorizing the suitability of its land for various uses and assessing the 
impact of land transfers on the environment. In deciding whether to 
approve certain transfers, the policy board must hold a hearing and 
consider specified factors the bill outlines. The bill generally provides a 
right of first refusal to the host municipality and state before selling 
unimproved real property.  
Like for RWA, the bill exempts the authority from property taxes, but 
it requires AWA to make annual payments in lieu of taxes to the host 
municipality, equal to the amount that would be otherwise due on the 
property other than on improvements made by the authority. As is the 
case for RWA, the bill specifies how property must be assessed and how 
the authority may appeal assessments.   
Like RWA, AWA must also reimburse host municipalities for 
expenses incurred to provide municipal services to improvements on 
AWA property (other than water pipes).   
As the law does for RWA, the bill requires municipalities (or the 
applicable water company’s governing board) to consent to AWA’s sale 
of water to its customers if another franchised water company or 
municipal water supply system currently serves them. Similarly, AWA 
must receive local consent before it extends wastewater services into 
previously unserved areas.   
Applicability of Other Laws and Oversight  
As is the case for RWA, the bill specifies that the charter it creates is 
the controlling authority for AWA, regardless of conflicting state laws 
or local ordinances, except its provisions generally do not exempt AWA 
from local zoning regulations. But certain facilities and structures must 
be allowed regardless of the zoning district.   
While PURA does not have jurisdiction over AWA, it (like RWA) is  2024SB-00501-R00SS1-BA.DOCX 
 
Researcher: RP 	Page 16 	6/26/24 
 
subject to the jurisdiction of the Department of Public Health (which 
regulates water quality and the adequacy of water supply) and the 
Department of Energy and Environmental Protection (which regulates 
water diversions, among other things). 
As existing law does for RWA, the bill (1) requires the AWA policy 
board to arrange for an annual audit, which must be made public and 
shared with town clerks; and (2) specifically gives the attorney general 
power to examine its books, accounts, and records. The bill also applies 
the same conflict of interest provisions to AWA that apply to RWA, 
including requiring board members and employees to disclose their 
financial interest in proposed contracts and orders and not participate 
in the deliberations or vote concerning the matter.   
Conforming Changes to RWA’s Charter  
As it does for AWA, the bill specifically authorizes RWA to borrow 
or bond to acquire Aquarion Water Company or any of its subsidiaries.   
The bill makes the acquisition of the company a noncore business 
activity, but it creates an exception in RWA’s charter allowing it to 
acquire the company without regard to existing law’s limitations on the 
ratio of its investments in core business to noncore businesses. Still, as 
under existing law, the authority cannot engage in noncore business 
activities that cost more than $1.5 million without the policy board’s 
approval.  
The bill gives RWA’s policy and governing boards authority to act on 
behalf of AWA until its boards are appointed. The bill also prohibits 
AWA’s boards from being appointed until PURA approves RWA’s or 
AWA’s acquisition of the company. RWA must notify appointing 
authorities when this occurs.  
The bill increases the governing board’s membership, if the company 
is acquired, from seven to 11 members. Under the bill, six of the 
members must reside in the RWA’s jurisdiction and five must reside in 
AWA’s. Under the bill, as described above, the membership of the AWA 
and RWA governing boards are identical. As current law does, the bill  2024SB-00501-R00SS1-BA.DOCX 
 
Researcher: RP 	Page 17 	6/26/24 
 
specifies how the members’ terms are staggered and establishes quorum 
requirements.   
Office of Consumer Affairs 
Existing law requires the RWA policy board to establish an Office of 
Consumer Affairs to act as the advocate for customer interests, 
including matters of rates, water quality and supply, and wastewater 
service quality. The bill requires the office to also advocate for AWA 
customers and gives it the same powers with respect to AWA, including 
the right to participate in regulatory and judicial proceedings involving 
AWA. Currently, RWA is responsible for all costs associated with the 
office. The bill instead makes RWA and AWA jointly responsible.  
§ 43 — SHPO PROJECT REVIEW 
Codifies in statute procedures for SHPO reviews to determine a proposed project’s impact 
on historic structures and landmarks; requires SHPO to make a determination within 30 
days and develop a mitigation plan with the project proponent under certain 
circumstances; allows a project proponent to request that DECD review the proposed plan 
The bill codifies in statute and revises procedures relating to certain 
project reviews under the Connecticut Environmental Policy Act 
(CEPA) by the State Historic Preservation Officer (SHPO). Currently, 
SHPO reviews projects under CEPA to determine whether there could 
be an impact on the state’s historic structures and landmarks, but 
neither CEPA nor its regulations specify requirements for SHPO’s 
reviews (see Background). 
Among other things, the bill requires SHPO to make an initial 
determination of a project’s impact within 30 days after receiving the 
information that it deems reasonably necessary to do so. If SHPO 
determines that there will be impact on historic structures and 
landmarks, it must propose a feasible alternative or mitigation plan in 
collaboration with the sponsoring agency; state entity (i.e., a state 
department, institution, or agency); or state funding recipient 
(collectively, “project proponent”). Under the bill, SHPO must annually 
post all mitigation agreements executed during the prior fiscal year on 
DECD’s website by January 1. 
The bill allows the project proponent, if it declines to execute the  2024SB-00501-R00SS1-BA.DOCX

proposed mitigation agreement, to request that the Department of 
Economic and Community Development (DECD) commissioner review 
the plan and recommend revisions. (SHPO is within DECD.) 
Additionally, it allows the sponsoring agency to conduct public scoping 
in keeping with CEPA if no agreement is reached. 
EFFECTIVE DATE: October 1, 2024 
SHPO REVIEW 
CEPA and Historic Preservation 
Generally, CEPA provides a declaration of state policy and 
establishes a process by which state agencies must identify and review 
their proposed actions that may significantly affect the environment 
(CGS § 22a-1a et seq.). Under CEPA, “actions which may significantly 
affect the environment” include individual activities or a sequence of 
planned activities proposed to be undertaken by state departments, 
institutions, or agencies, or funded in whole or in part by the state, 
which could have a major impact on, among other things, historic 
structures and landmarks (CGS § 22a-1c). The bill similarly defines this 
term, except that it expressly excludes the following actions: 
1. major federal actions under the National Environmental Policy 
Act,  
2. undertakings under the National Historic Preservation Act, and 
3. those affecting archaeological or sacred sites. 
By law and under the bill, “historic structures and landmarks” means 
any building, structure, object, or site that is significant in American 
history, architecture, archaeology, and culture or property used in 
connection with it, including sacred sites and archaeological sites (CGS 
§ 10-410). Archaeological sites are locations where material evidence 
exists that is at least 50 years old of past human life and culture in the 
state. Sacred sites are spaces of ritual or traditional significance of Native 
American culture and religion that are eligible for listing on the national 
or state registers of historic places.  2024SB-00501-R00SS1-BA.DOCX

Initial Determination  
Under the bill, a sponsoring agency may request that SHPO make an 
initial determination on whether a project proponent’s proposed 
individual activities or sequence of planned activities could have an 
impact on the state’s historic structures and landmarks (and potentially 
significantly affect the environment). Although CEPA does not define 
“sponsoring agency,” under CEPA regulations each agency responsible 
for recommending or initiating an action is considered a sponsoring 
agency (Conn. Agencies Regs., § 22a-1a-2(a)). 
The bill requires SHPO to make the initial determination within 30 
days after receiving information it deems reasonably necessary to do so. 
SHPO must (1) consider all information the project proponent provides 
in making this determination and (2) provide a written determination to 
the proponent if it finds that there is no effect on historic structures and 
landmarks (or the environment will not be significantly affected because 
there is no impact on historic structures and landmarks). Under the bill, 
SHPO’s initial determination that there is no effect or impact is final.  
Determination of Effect or Impact 
Feasible Alternative. Under the bill, when SHPO makes an initial 
determination that a proposed activity or activities will have an effect or 
impact on historic structures and landmarks, it must, if possible, 
propose a prudent or feasible alternative to avoid these impacts. It is 
required to do so in collaboration with the project proponent.   
If SHPO and the project proponent agree on an alternative, SHPO 
must provide a written determination to the proponent that the 
alternative will have no effect on historic structures and landmarks (or 
that it is not within the category of actions that may significantly affect 
the environment because there is no impact on historic structures and 
landmarks). This determination is final.  
Mitigation Plan. Under the bill, if SHPO and the project proponent 
do not agree on an alternative, SHPO must provide the proponent with 
a written determination that the activity or activities will have an effect 
or impact on historic structures and landmarks, as discussed above.  2024SB-00501-R00SS1-BA.DOCX 
 
Researcher: RP 	Page 20 	6/26/24 
 
After SHPO makes this determination, it must propose a mitigation plan 
requiring the project proponent to mitigate the impact. It must do so in 
collaboration with the project proponent (and regardless of CEPA 
provisions on environmental impact evaluations (EIEs)).  
In creating the mitigation plan, the bill requires SHPO to consider the 
following:  
1. all pertinent information about the activity or activities that may 
affect the plan (the project proponent must submit this to SHPO, 
to the extent possible); and 
2. information DECD provides on the economic impact of the 
proposed activity or activities and mitigation plan (SHPO must 
consult with the DECD commissioner or his designee on this 
topic). 
The bill requires SHPO, within 45 days after receiving information 
from the proponent, to memorialize the mitigation plan in a proposed 
agreement that the project proponent may execute. When SHPO gives 
the mitigation agreement to the project proponent, it must also notify 
the proponent that it may request DECD to review the agreement (see 
below). 
Under the bill, if the project proponent executes the original 
agreement or a revised agreement (see below), then SHPO must also do 
so. Executing the original or revised agreement constitutes (1) a final 
determination by SHPO and (2) that SHPO is satisfied the effect on 
historic structures and landmarks will be mitigated based on the terms 
of the agreement.  
DECD Review. The bill allows the project proponent, if it declines to 
execute the mitigation agreement described above, to request the DECD 
commissioner to review the proposed agreement and recommend 
revisions. If the proponent chooses to make this request, it must do so 
within 15 days after SHPO provides it with the proposed mitigation 
agreement. The request must be as the commissioner prescribes and 
may include a request for a conference with the commissioner, SHPO,  2024SB-00501-R00SS1-BA.DOCX 
 
Researcher: RP 	Page 21 	6/26/24 
 
project proponent, and any other interested party. 
Within 30 days after receiving the request, the commissioner must 
hold the conference (if requested) and make recommendations (if any) 
for revising the proposed mitigation agreement, which SHPO must 
incorporate into a revised mitigation agreement that the project 
proponent may then execute. If the commissioner does not recommend 
revisions, the proponent may elect to execute the originally proposed 
agreement. 
Public Scoping If Agreement Not Executed. The bill requires a 
sponsoring agency to conduct an early public scoping under CEPA if no 
mitigation agreement is executed, despite SHPO proposing a mitigation 
plan as described above. Generally, public scoping is when the 
sponsoring agency solicits comments from other agencies and the public 
about the proposed action’s environmental effects and whether an EIE 
is required (CGS § 22a-1b(b)). 
Background 
CEPA Overview. Generally, CEPA provides a declaration of state 
policy and establishes a process by which state agencies must identify 
and review their proposed actions that may significantly affect the 
environment (CGS § 22a-1a et seq.). CEPA reviews have three primary 
stages: 
1. an initial assessment by a sponsoring agency (i.e., the agency 
administering or funding the project) to determine whether 
public scoping is required; 
2. a public scoping process to determine whether an EIE is required 
(CGS § 22a-1b(b)); and 
3. an EIE, which is the most extensive level of review under CEPA 
(CGS § 22a-1b(c)). 
SHPO’s reviews generally occur at the first stage of the process (i.e., 
before public scoping). During this stage, agencies consult an 
environmental classification document, which lists examples of agency  2024SB-00501-R00SS1-BA.DOCX 
 
Researcher: RP 	Page 22 	6/26/24 
 
actions that typically require (or do not require) public scoping. If the 
sponsoring agency determines that its action does not have the potential 
to significantly affect the environment, then it does not proceed to public 
scoping or EIE. 
SHPO. SHPO is located within DECD and has responsibilities under 
both federal and state law, including the following: 
1. historic designations to the National and State Registers of 
Historic Places; 
2. regulatory review and compliance related to the National 
Historic Preservation Act (i.e., Section 106 reviews) and CEPA; 
3. local historic preservation programs; 
4. federal and state tax credit programs; and 
5. state museums. 
The term “SHPO” is often used interchangeably to refer to either the 
“State Historic Preservation Office” or the “State Historic Preservation 
Officer.” In practice, the responsibilities of the designated officer are 
fulfilled by the office as a whole.
