LEGISLATIVE COUNSEL’S DIGEST

AB 2320, as amended, Calderon. Unmanned aircraft begin delete systems: regulation. end delete begin insert systems. end insert

begin insert

(1) Existing federal law, the Federal Aviation Administration Modernization and Reform Act of 2012, provides for the integration of civil and public unmanned aircraft systems, commonly known as drones, into the national airspace system.

end insert begin insert

Existing state law generally authorizes a court to issue an order for the protection of certain persons, including, among others, the victims of domestic violence, elder and dependent adult abuse, workplace violence, and civil harassment. Under existing law, an intentional and knowing violation of those types of protective orders is a misdemeanor. If the violation results in physical injury, or occurs within specified time periods of a previous violation, existing law imposes additional penalties. Existing law also makes the crime of stalking another person, as defined, punishable as a misdemeanor or felony. Existing law makes it a felony to commit that offense when there is a temporary restraining order, injunction, or any other court order in effect prohibiting the behavior.

end insert begin insert

This bill would specifically prohibit a person who is prohibited from coming within a specified distance of another person, from operating an unmanned aircraft system in a way that causes an unmanned aircraft, as those terms are defined, to fly within the prohibited distance of the other person or from capturing images of the other person by using an unmanned aircraft system. By creating a new crime, the bill would impose a state-mandated local program.

end insert begin insert

(2) Existing law requires a person who has been convicted of specified sex offenses to register with local law enforcement authorities as a sex offender.

end insert begin insert

This bill would prohibit a person required to register pursuant to those provisions for an offense committed on or after January 1, 2017, from operating an unmanned aircraft system. Because a violation of that provision would be a crime, the bill would impose a state-mandated local program.

end insert begin insert

(3) Existing law provides that every person who goes to the scene of an emergency or stops at the scene of an emergency for the purpose of viewing the scene or the activities of police officers, firefighters, emergency medical or other emergency personnel, or military personnel coping with the emergency in the course of their duties during the time it is necessary for emergency vehicles or those personnel to be at the scene of the emergency or to be moving to or from the scene of the emergency for the purpose of protecting lives or property, unless it is part of the duties of that person’s employment to view that scene or activities, and thereby impedes police officers, firefighters, emergency medical or other emergency personnel, or military personnel in the performance of their duties in coping with the emergency, is guilty of a misdemeanor.

end insert begin insert

This bill would include, for purposes of these provisions, the operation or use of an unmanned aircraft system in the definition of a person. By expanding the scope of a crime, this bill would impose a state-mandated local program.

end insert begin insert

(4) Existing law makes a person who willfully, maliciously, and repeatedly follows or willfully and maliciously harasses another person and who makes a credible threat with the intent to place that person in reasonable fear for his or her safety, or the safety of his or her immediate family, guilty of the crime of stalking, punishable as a misdemeanor or a felony.

end insert begin insert

This bill would specifically include, for purposes of these provisions, the operation or use of an unmanned aircraft system in the definition of a person.

end insert begin insert

(5) Existing law makes a person who knowingly brings into certain correctional facilities or certain other places where prisoners or inmates of those facilities are located, any alcoholic beverage, any drugs, other than controlled substances, in any manner, shape, form, dispenser, or container, or any device, contrivance, instrument, or paraphernalia intended to be used for unlawfully injecting or consuming any drug other than controlled substances, without having authority so to do by the rules of the correctional facility, guilty of a felony.

end insert begin insert

This bill would specifically include, for purposes of these provisions, the operation or use of an unmanned aircraft system in the definition of a person.

end insert begin insert

(6) The bill would make related legislative findings and declarations and would include a statement of legislative intent.

end insert begin insert

(7) The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement.

end insert begin insert

This bill would provide that no reimbursement is required by this act for a specified reason.

Existing federal law, the Federal Aviation Administration Modernization and Reform Act of 2012, provides for the integration of civil and public unmanned aircraft systems, commonly known as drones, into the national airspace system.

end delete begin delete

This bill would state the intent of the Legislature to enact legislation that will regulate unmanned aircraft systems.

end delete

Vote: majority. Appropriation: no. Fiscal committee:  begin delete no end delete begin insert yes end insert . State-mandated local program:  begin delete no end delete begin insert yes end insert .

The people of the State of California do enact as follows:

begin insert

begin insert SECTION 1. end insert   

end insert

begin insert (a) end insert begin insert   end insert begin insert The Legislature finds and declares all of the
following: end insert

begin insert

(1) The Federal Aviation Act of 1958 established the Federal
Aviation Administration (FAA) and made the FAA responsible for
the control and use of navigable airspace within the United States.

end insert begin insert

(2) The FAA regulates unmanned aircraft systems, also known
as drones.

end insert begin insert

(3) Public entities, including law enforcement agencies,
firefighter units, border and port patrols, disaster relief workers,
search and rescue personnel, qualifying public universities,
military training facilities, and other government operational
mission units, may operate unmanned aircraft systems by applying
for a Certificate of Waiver or Authorization from the FAA.

end insert begin insert

(4) The FAA is in the process of developing rules that are
intended to safely integrate small unmanned aircraft systems into
the national airspace system and that, following issuance of a
Notice of Proposed Rulemaking and public comment period, are
expected to be released in 2016 or 2017.

end insert begin insert

(5) The small unmanned aircraft system rules are anticipated
to be similar to the current hobbyist rules for operations of model
unmanned aircraft systems that limit the area of operation to
low-risk and controlled environments and the size of the system
to less than 55 pounds.

end insert begin insert

(6) While the FAA is developing the small unmanned aircraft
system rules, private commercial entities on a
company-by-company basis may apply to the FAA for a Section
333 exemption from the current rules for manned aircraft by
showing that the entity operates with at least an equivalent level
of safety. The FAA has granted over 1,900 Section 333 exemptions
to date for the commercial operation of unmanned aircraft systems
in the photography, film, utilities, energy, infrastructure, real
estate, agricultural, and construction industries.

end insert begin insert

(7) In addition to being used in military training and operations
and public safety areas, unmanned aircraft systems may be used
in a wide variety of activities, including oil and natural gas pipeline
inspection, transportation, natural disaster aid, search and rescue,
precision agriculture, natural resource and environmental
protection, bridge and infrastructure inspection, public utility
support, construction and building inspection, surveying, golf
course marketing, wind turbine inspection, realtor marketing
photography, and prison monitoring.

end insert begin insert

(8) While the public has expressed concerns with the operation
of unmanned aircraft systems, including privacy and safety issues,
there are benefits that may be realized by the state, including the
state’s various industry sectors, from conducting research on
unmanned aircraft systems in the state and developing,
manufacturing, and operating unmanned aircraft systems in the
state.

end insert begin insert

(9) The FAA has warned that a “patchwork quilt” of inconsistent
regulation raises substantial safety concerns, impedes innovation,
and makes it virtually impossible for end-users to understand the
rules for operating unmanned aircraft systems.

end insert begin insert

(b) (1) It is the intent of the Legislature that a person be
prohibited from, without the owner or business operator’s written
consent, operating or using an unmanned aircraft system to
knowingly and intentionally fly within 250 feet of the perimeter of
any critical infrastructure facility for the purpose of conducting
surveillance of the facility, gathering evidence or collecting
information about the facility, or photographically or electronically
recording critical infrastructure data.

end insert begin insert

(2) For purposes of this subdivision, “critical infrastructure
facility” means an airport, an electrical power generation system,
a petroleum refinery, a manufacturing facility that utilizes any
combustible chemicals either in storage or in the process of
manufacturing, a chemical or rubber manufacturing facility, or a
petroleum or chemical storage facility.
