1.1 Nevada Statutes & Administrative Code (NRS 555, NRS 586, NAC 555)

Nevada Statutes & Administrative Code (NRS 555, NRS 586, NAC 555)

Pesticide regulation in Nevada is governed by a comprehensive legal framework established by the Nevada Legislature and enforced by the Nevada Department of Agriculture (NDA). Certified applicators and pest control businesses must operate in strict compliance with state statutes and administrative codes to protect public health, non-target organisms, agricultural commodities, and Nevada's fragile desert ecosystems. The primary legal pillars governing pesticides in Nevada consist of Nevada Revised Statutes (NRS) Chapter 555, NRS Chapter 586, and Nevada Administrative Code (NAC) Chapter 555.

Nevada Revised Statutes Chapter 555 (NRS 555): Pest Control Regulations

NRS Chapter 555, titled "Control of Insects, Pests and Noxious Weeds," represents the primary state statute regulating custom pest control applicators, commercial pest control businesses, and the management of agricultural pests and invasive plants across Nevada.

Legislative Intent and Statutory Scope

The statute establishes clear regulatory boundaries to ensure that individuals applying pesticides for hire, or applying restricted-use pesticides, possess proven technical competence, follow approved application practices, and maintain environmental safety standards. NRS 555 governs:

1. Licensing of Pest Control Operators and Businesses — Mandates that no person may engage in the business of pest control for hire within Nevada without obtaining an appropriate license from the NDA.
2. Supervision and Operational Standards — Requires certified principals to oversee daily operations, employee activities, and equipment safety.
3. Noxious Weed Management and Eradication — Defines state-listed noxious weeds, categorizes invasive plant threats, and authorizes county weed control districts and state officials to compel landowners to control declared noxious species.
4. Protection of Public Resources and Groundwater — Mandates measures to prevent pesticide contamination of groundwater, surface water, wildlife habitats, and human habitation.

Noxious Weed Classification under NRS 555

Nevada law authorizes the NDA Director to designate non-native plant species as noxious weeds when they threaten agriculture, livestock, public health, or native ecosystems. Noxious weeds are grouped into three statutory categories:

• Category A Weeds: Invasive plants that are generally not present or are highly limited in distribution across Nevada. Immediate eradication is mandatory wherever discovered (e.g., African Rue, Squarrose Knapweed).
• Category B Weeds: Invasive plants established in specific counties but not ubiquitous statewide. Suppression and containment are required to prevent spread into uninfested regions (e.g., Musk Thistle, Russian Olive).
• Category C Weeds: Invasive plants widely distributed across Nevada. Control is enforced at the discretion of the NDA or county weed control districts to protect adjacent agricultural lands (e.g., Puncturevine, Hoary Cress).

Nevada Revised Statutes Chapter 586 (NRS 586): The Nevada Pesticides Act

While NRS 555 regulates the people and businesses applying pesticides, NRS Chapter 586, titled the "Nevada Pesticides Act," regulates the pesticide products themselves before they can be legally distributed, sold, or offered for sale within the state.

Product Registration Requirements

Under NRS 586.250 through 586.300, every pesticide product distributed, sold, transported, or offered for sale within Nevada must be registered annually with the Nevada Department of Agriculture. Registration applications submitted by chemical manufacturers or distributors must include:

• The brand name and full product trade name.
• A complete copy of the product labeling, including directions for use, signal words, and precautionary statements.
• The EPA Registration Number and EPA Establishment Number.
• The name and address of the manufacturer or registrant.
• Payment of the statutory state product registration fee.

Prohibition of Adulteration and Misbranding

NRS 586 strictly prohibits the distribution, sale, or transportation of any pesticide product that is adulterated or misbranded:

• Adulterated Pesticides: A pesticide is legally adulterated if its strength, purity, or composition falls below the professed standard or quality expressed on its labeling, or if any substance has been substituted wholly or in part for the active ingredient.
• Misbranded Pesticides: A pesticide is misbranded if its labeling contains false or misleading statements, lacks required EPA registration or establishment numbers, fails to display clear signal words (e.g., DANGER, WARNING, CAUTION), or lacks adequate instruction to protect human health and the environment.

Nevada Administrative Code Chapter 555 (NAC 555): Administrative Rules

NAC Chapter 555 contains the specific administrative rules promulgated by the Nevada Department of Agriculture under the authority granted by NRS 555 and 586. While statutes set broad legal mandates, administrative codes define the day-to-day regulatory procedures that applicators must follow.

Key Administrative Sections in NAC 555

• NAC 555.250–555.397: Custom application of pesticides — definitions, license types (primary principal, location principal, principal, operator, demonstration and research specialist, agent), licensing fields and categories, examination standards, continuing education, and fee schedules.
• NAC 555.400–555.510: Standards of practice — required records and reports (NAC 555.410), prohibited materials, service vehicle markings, pre-construction termite treatments, wood-destroying pest reports, protection of bees (NAC 555.470), and fumigation procedures (NAC 555.510).
• NAC 555.5201–555.530: Nonfood/nonfeed site designations, administrative complaints, and the schedule of administrative fines (NAC 555.530).
• NAC 555.600–555.710: Certified applicators — adoption of the federal competency standards in 40 CFR 171.103/171.105 (NAC 555.615), certification categories, standards of competency, examinations (general plus category, 70% passing score), certificate renewal (12 CEUs per 4 years or re-examination), and certificate fees ($50 per examination period).

Regulatory Authority: Nevada Department of Agriculture (NDA)

The Nevada Department of Agriculture (NDA), acting through its Division of Plant Health and Compliance, serves as the sole state lead agency responsible for enforcing Nevada pesticide laws and implementing federal standards delegated under cooperative agreements with the U.S. Environmental Protection Agency (EPA).

Statutory Powers of the NDA Director

Under NRS 555.2605 through 555.470, the Director of the Department of Agriculture holds extensive statutory authority to enforce compliance:

• Inspection Authority: NDA inspectors have legal authority to enter public or private premises, commercial facilities, agricultural fields, storage structures, and application sites at reasonable times to inspect application equipment, observe pesticide applications, examine pesticide storage facilities, take soil, plant, or water samples, and inspect mandatory applicator records.
• Subpoena and Examination Powers: The Director may compel testimony, issue subpoenas for witnesses, and require the production of business books, records, and shipping invoices during formal investigations.
• Corrective Orders and License Actions: If an NDA inspector discovers an unsafe application practice, fraudulent recordkeeping, or unlicensed pest control activity, the Director may issue an order requiring the violator to take appropriate corrective action (NRS 555.470) and, after notice and opportunity for a hearing, may deny, suspend, revoke, or modify the violator's license or certificate (NRS 555.359; NAC 555.710).
• Seizure of Non-Compliant Products: Under NRS 586.960, any pesticide or device that is unregistered, adulterated, misbranded, or otherwise non-compliant is liable to be seized and confiscated through a district-court condemnation process, and disposed of by destruction or sale as the court directs. At the federal level, the EPA wields the parallel Stop-Sale, Stop-Use, or Removal Order authority under FIFRA Section 13 for products anywhere in the United States.

Enforcement Actions and Statutory Penalties

Nevada law provides severe administrative, civil, and criminal penalties for individuals or businesses operating in violation of NRS 555, NRS 586, or NAC 555.

Administrative Fines

Under NRS 555.460 and NRS 555.470, the Director may assess administrative fines following an administrative hearing or notice of violation. The maximum administrative fine is up to $5,000 per violation, per day. Each day a violation continues, or each separate application conducted in violation of state law, constitutes a distinct and separate punishable offense. Fine amounts follow the schedule adopted in NAC 555.530 (typically $100 to $1,000 per violation, rising to $1,001 to $5,000 for serious violations).

Administrative Penalties Hierarchy

1. Warning Letters / Notices of Non-Compliance: Issued for minor administrative errors or first-time technical infractions that do not threaten public health or the environment.
2. Administrative Fines: Assessed up to $5,000 per violation based on severity, prior compliance history, degree of negligence, and potential environmental harm.
3. License Modification, Suspension, or Revocation: The Director may suspend or permanently revoke an applicator's or business's license for fraudulent recordkeeping, gross negligence, applying pesticides contrary to label directions, or operating without insurance.
4. Criminal Prosecution Referral: Willful or fraudulent violations may be referred to local district attorneys or the Nevada Attorney General for criminal prosecution as misdemeanors or gross misdemeanors.
