Indiana : 2025 Regular Session : BILL HB1335
Weather control.
Sponsor: Rep Lorissa Sweet & Rep Lindsay Patterson
Bill Details
Weather control. Prohibits a person who has the intent of affecting the intensity of sunlight, temperature, or weather from discharging a chemical or apparatus into the atmosphere, except in certain circumstances. Establishes that a violation is a Class B misdemeanor.
GeoLawWatch Bill Summary
Primary Prohibition: The bill creates a new Chapter 16 ("Weather Control") in Indiana Code Title 13 (Environmental Law). It prohibits any person from discharging a chemical or apparatus into the atmosphere with the intent of affecting the intensity of sunlight, temperature, or weather.
Exemption: The prohibition does not apply to persons operating misting devices or other temperature regulation devices to warm or cool individuals on the same premises as the device. This narrow exemption covers items like patio misters, outdoor heaters, and similar localised comfort devices.
Penalties: A violation constitutes a Class B misdemeanour, punishable by up to 180 days in jail and a fine of up to $1,000. Unlike its Senate companion bill (SB 364), HB 1335 contains no felony enhancement for violations resulting in serious bodily injury or death. Enforcement: The bill does not designate a specific enforcement agency or create monitoring mechanisms. Prosecution would presumably fall to county prosecutors under standard criminal procedures.
Notable Absence: The bill contains no exemptions for existing weather modification activities (such as cloud seeding operations), federally authorised activities, emergency response, agricultural applications, scientific research, or state-permitted activities. The prohibition is structured around intent rather than specific substances or methods.
History
HB 1335 was introduced by Representative Lorissa Sweet on January 13, 2025, the opening day of Indiana's 124th General Assembly, with Representative Patterson listed as coauthor from the outset. The bill received its first reading the same day and was referred to the Committee on Environmental Affairs, a routing that contrasts with its Senate counterpart, SB 364, which went to Corrections and Criminal Law.
The two bills are substantively identical in their prohibition language but differ significantly in penalty structure: HB 1335 imposes only a Class B misdemeanour, while SB 364 includes felony enhancement provisions. This parallel filing suggests either a coordinated strategy to determine which version gains traction or a genuine policy disagreement over the appropriate enforcement severity. Indiana's 2025 legislative session has a crossover deadline of February 20, 2025, meaning the bill must pass the House and move to the Senate by that date to remain viable. Final adjournment is scheduled for April 24, 2025.

Explanation of State Revenues
The bill provides that a person who discharges a chemical or apparatus into the atmosphere with the intent of affecting the intensity of sunlight, temperature, or weather commits a Class B misdemeanor. If additional court cases occur and fines are collected, revenue to both the Common School Fund and the state General Fund would increase. The maximum fine for a Class B misdemeanor is $1,000. Criminal fines are deposited in the Common School Fund. The total fee revenue per case would range between $113 and $138. The amount of court fees deposited will vary depending on whether the case is filed in a court of record or a municipal court. The following linked document describes the fees and distribution of the revenue: Court fees imposed in criminal, juvenile, and civil violation cases.
Explanation of Local Expenditures
A Class B misdemeanor is punishable by up to 180 days in jail. The average cost per day to incarcerate a prisoner is approximately $64.53 based on the per diem payments reported by U.S. Marshals to house federal prisoners in 11 county jails across Indiana during CY 2021.
Explanation of Local Revenues
If additional court actions occur and a guilty verdict is entered, more revenue will be collected by certain local units. If the case is filed in a court of record, the county general fund will receive $47.40 and qualifying municipalities will receive a share of $3.60. If the case is filed in a municipal court, the county receives $30, and the municipality will receive $46.
