718 The following Fiscal Impact Statement and Bill Analysis are prepared for the benefit of the members of the General Assembly, solely for purposes of information, summarization and explanation and do not represent the intent of the General Assembly or either chamber thereof for any purpose.
In general, fiscal impacts are based upon a variety of informational sources, including the analyst’s professional knowledge.
Whenever applicable, agency data is consulted as part of the analysis, however final products do not necessarily reflect an assessment from any specific department.
OFA Fiscal Note State Impact:
See Below Municipal Impact:
None Explanation The bill potentially results in increased costs or savings to various state agencies since it mandates use of certain biodiesel blends beginning in FY 26.
The cost or savings is unknown and dependent on future fuel prices.
Recent national average retail fuel prices for biodiesel (B20) have been $0.04/gallon less than the conventional diesel gallon equivalent.
1 However, it should be noted that price data specifically for Connecticut is limited and may differ substantially from the U.S.
as a whole given the limited local market for such fuels compared to other states.
The Out Years The annualized ongoing fiscal impact identified above would continue into the future subject to fuel prices.

It also requires, by certain dates, all (1) diesel fuel sold or offered for sale in retail establishments from April to November to use increasing amounts of biodiesel and (2) diesel-operated vehicles, vessels, and construction equipment in the state fleet to use increasing percentages of biodiesel from April to November.
EFFECTIVE DATE:
Upon passage, except the provisions on animal testing are effective October 1, 2025.
ANIMAL TESTING BAN The bill prohibits entities that produce or test chemicals, ingredients, products formulations, or products (manufacturers and contract testing facilities)fromconductinganimaltestingifthereisanalternativetesting method.

An alternative test method is one that:
1.
providesinformationofequivalentorbetterscientificqualityand relevance than animal test methods;
2.
has been identified by a validation body (an organization that facilitates development, validation, and regulatory acceptance of HB6278 / File No.
718 6 HB6278 File No.
718 testing methods that reduce, refine, or replace the use of animals in testing, such as the Interagency Coordinating Committee on the Validation of Alternative Methods) and adopted by the relevant federal agency or program within an agency responsible for regulating the product or activity for which the test is being conducted;
and 3.
does not use animals, or, when there is no test method available that does not use animals, uses the fewest animals possible and reduces their suffering or stress to the greatest extent possible.
Exceptions The bill’s prohibition does not apply to animal testing for medical research into the (1) causes, diagnosis, treatment, control, or prevention of physical or mental diseases or (2) development of devices, drugs, biomedical products, and any products other than cosmetics regulated by the U.S.
Food and Drug Administration.
But this exception does not apply to ingredients that (1) were formerly used in a drug;
(2) were tested for drug use through animal testing to be characterized as safe;
and (3) are being proposed for use in something that is not a biomedical product, medical device, or drug.
The bill does not prohibit testing methods that do not use animals (i.e.
live vertebrate nonhuman animals).
BIODIESEL REQUIREMENTS During the months of April to November, the bill requires retail diesel sold or offered for sale in the state to contain larger percentages of biodiesel, by these dates:
1.
at least 5% by July 1, 2025;
2.
at least 10% by July 1, 2027;
and 3.
at least 20% by July 1, 2029.
Similarly, from April to November, all diesel operated vehicles, vessels, and construction equipment that is part of the state fleet must HB6278 / File No.

718 use larger percentages of biodiesel, by these dates:
1.
at least 5% by July 1, 2025, and 2.
at least 20% by July 1, 2027.
Under the bill, “biodiesel” is fuel derived from vegetable oils or animal fats that is designated as B100 (i.e.
100% biodiesel without petroleum diesel mixed in) and meets the requirements of D6751 of the American Society for Testing and Materials (i.e.
a biodiesel specification).
This type of biodiesel is referred to as “pure biodiesel” and is typically used to create fuel blends.
