Not controlled by the State except through the concealed firearms pre-emption. 14-415.23. If the municipality does not prohibit OC, then you are okay. It does seem that many places, in their rush to change their ordinances to comply with state law, seemingly forgot to include OC. Far be it from me to point out that regulating CC does not affect anything else.

Persons wishing to possess or use pyrotechnics in connection with a public exhibition, such as a public celebration, shall file an application for a special use permit with the park superintendent. All applicants shall enter an indemnification agreement with the Department and obtain general liability and property damage insurance, with limits as determined by the Secretary or designee, which are reasonably necessary to cover possible liability for damage to property and bodily injury or damage to persons which may result from, or be caused by, the public exhibition of pyrotechnics or any
act(s) or omission(s) on the part of the applicant(s) or the applicant's agents, servants, employees, or subcontractors presenting the public exhibition. The Division Director or designee may deny an application as deemed necessary to protect the public health, safety, and welfare, or to protect the natural resources of the park unit.

Grapeshot, your cite is from HB 937. It has been fully integrated into the current Chapter 14 Criminal laws. 14-269.3 has nothing to do with parks unless an admission is required to an assembly (event) within the park.
