1.8 Inspections, Prohibited Acts & Penalties

Key Takeaways

  • DEEP officers may enter at reasonable times to observe applications, inspect equipment, investigate damage claims, and take samples under CGS § 22a-59.

  • Using a pesticide inconsistently with its labeling and falsifying records are grounds to suspend or revoke Connecticut certification.

  • A commercial applicator who knowingly violates Chapter 441 faces a fine up to $5,000, up to one year in jail, or both.

  • Uncertified commercial application, or operators doing supervisory work, draws civil penalties of $1,000 to $2,000 per day.

  • Employee acts are deemed acts of the employer under CGS § 22a-63(d), so a business is liable for its technicians' violations.

1.8 Inspections, Prohibited Acts & Penalties

Knowing what happens when the rules are broken is part of every Connecticut exam. CGS Chapter 441 gives DEEP inspection and warrant powers (§ 22a-59), lists prohibited acts (§ 22a-61), sets grounds for denying, suspending, or revoking certification (§ 22a-61(f)), and establishes criminal fines and civil penalties (§ 22a-63). Separate penalty provisions cover businesses (§ 22a-66h), notice violations (§ 22a-66a(l)), and chlorpyrifos (§ 22a-61c).


DEEP Inspection Powers — CGS § 22a-59

DEEP officers or employees designated by the commissioner may enter at reasonable times any establishment or place where pesticides or devices are used, held for use, or held for distribution or sale, in order to:

  1. Observe pesticide applications.
  2. Determine whether the applicator is or should be certified.
  3. Determine whether the applicator has a proper permit to apply restricted use pesticides.
  4. Inspect equipment or devices used to apply pesticides.
  5. Inspect or investigate damage claims.
  6. Inspect or sample where pesticides are used, stored, distributed, or sold.
  7. Sample pesticides, devices, containers, and labeling released for shipment.
  8. Sample pesticides or devices that have been used, and their containers and labeling.

Procedural protections

  • Before inspecting a place where pesticides are held for distribution or sale, the officer presents credentials and a written statement of the reason, including whether a violation is suspected. If none is suspected, another sufficient reason is given in writing.
  • Inspections must begin and end with reasonable promptness.
  • When samples are taken, the officer gives the owner or operator a receipt and, on request, a portion of each sample equal to what was kept. Analyses may be done by the Connecticut Agricultural Experiment Station, and results go promptly to the owner and to DEEP.
  • When there is reason to believe a violation has occurred, officers may obtain warrants for entry, inspection of shipment records, and seizure of violative pesticides or devices (§ 22a-59(b)).

Applicators must also cooperate with record inspections. Refusing to keep required records, or refusing inspection or sampling, is itself a prohibited act (§ 22a-61(b)(2)).


Prohibited Acts — CGS § 22a-61

Selling and distributing (§ 22a-61(a))

It is unlawful to use, distribute, sell, hold for sale, ship, or deliver:

  • any pesticide not registered in Connecticut;
  • a registered pesticide with claims that differ substantially from its registration, or a composition that differs from its registration;
  • a pesticide not colored or discolored as required;
  • any adulterated or misbranded pesticide, or a misbranded device.

Adulterated means its strength or purity falls below the labeled standard, a substance has been substituted, or a valuable constituent has been removed (§ 22a-47(b)). Misbranded includes false or misleading labeling, non-conforming packaging, or imitating another pesticide (§ 22a-47(r)).

Use and conduct (§ 22a-61(b), (d), (e))

Key acts that applicators can commit:

  • To detach, alter, deface, or destroy any labeling required under FIFRA.
  • To refuse to keep records or refuse inspection or sampling.
  • To use any registered pesticide in a manner inconsistent with its labeling or with Connecticut restrictions — the state counterpart of FIFRA § 12(a)(2)(G).
  • To make restricted or permit-use pesticides available for use, or use them, other than as classified.
  • To use a pesticide under an experimental use permit contrary to the permit.
  • To violate any stop-sale, suspension, or cancellation order.
  • To violate the school pesticide laws (§§ 10-231b to 10-231d) or the restricted-sale rules (§ 22a-57).
  • To knowingly falsify any application, record, or report.
  • For an uncertified person to advertise or solicit commercial application (§ 22a-61(d)).
  • For an operational certificate holder to perform, advertise, or solicit any activity requiring a supervisory certificate (§ 22a-61(e)).

Public officials performing official duties are exempt from § 22a-61's prohibitions unless they are using restricted use pesticides (§ 22a-61(c)(3)).


Grounds to Deny, Suspend, or Revoke Certification — § 22a-61(f)

DEEP may refuse to grant or renew certification, or may suspend or revoke it after a hearing. Any violation of the pesticide laws applicable to certified applicators is a ground. The statute specifically lists:

GroundExample on the job
(A) Use inconsistent with labeling or state/federal restrictionsExceeding the label rate; applying to an unlisted site
(B) Falsifying, or refusing to keep, required recordsBack-filling records after an inspection notice
(C) Applying pesticides known in the trade to be ineffective or improperUsing a grass herbicide on broadleaf weeds
(D) Operating faulty or unsafe equipmentLeaking hoses, missing anti-siphon devices
(E) Faulty, careless, or negligent applicationDrift onto a neighbor's vegetable garden
(F) Neglecting or refusing to comply with the law, regulations, or DEEP ordersIgnoring a corrective order
(G) Fraud or misrepresentation in applying for or renewing a permit or certificationMisstating experience or identity
(H) Not complying with limits in a permit or certificationTreating beyond an aquatic permit's limits
(I) Aiding or abetting evasion of the lawLetting an uncertified worker spray alone
(J) Allowing one's permit or certification to be used by another person"Renting" a supervisor's number to another company
(K) False or misleading statements during an inspection or investigationMisstating which product was used
(L) Working, paid or not, in a category without certificationA 7A supervisor treating turf for ticks
(M) Failing to submit required recordsNot filing the January 31 summary

DEEP must also review a certification when the applicator is convicted of a criminal FIFRA violation, receives a final EPA civil penalty order under FIFRA, or has a certification revoked in another state (§ 22a-61(f)(2)). After suspension or revocation, the person may not apply for a new certificate until the period set by the commissioner has passed.

Chlorpyrifos golf course or nonagricultural useCivil penalty up to $2,500 (§ 22a-61c)

Vicarious responsibility

Under § 22a-63(d), the act, omission, or failure to act of any officer, agent, or employee is deemed also to be the act of the person employing them. A business owner cannot escape liability by blaming a technician; § 22a-66i applies the same rule to registered businesses.

Federal penalties also apply

Connecticut penalties are in addition to federal FIFRA penalties (Section 2.1). DEEP must review a certificate after a federal criminal conviction or final EPA civil penalty order.

Important

The operator manual summarizes the point: "To possess a junior operator's certificate is a privilege. Remember that it can be suspended or revoked if pesticides are misused or if pesticide laws and regulations are not followed."
