1.3 Indiana Recordkeeping, Insurance & Enforcement

Key Takeaways

  • Under 355 IAC 4-4-1, commercial applicators must keep records of every restricted use pesticide application containing 13 mandatory elements, created by the thirtieth day from the date of application.
  • The 13 elements are customer/property owner name, site address or coordinates, name of the person applying, name and license number of the responsible commercial applicator, date, start and stop times, description of the site treated, principal pests, acreage or area treated, brand name, EPA registration number, and amount of product used.
  • Indiana's record rule does NOT require application rate, carrier volume, air temperature, wind speed, or wind direction — those belong to other states' rules and to specific labels such as dicamba over-the-top products.
  • Application records are kept two (2) years; direct-supervision and WPS training records are kept two (2) years; bulk storage containment inspection records are kept three (3) years.
  • Civil penalties under IC 15-16-5-66 are graded by the seriousness of the act, not by how many times you have offended: up to $250 (only after a prior warning for the same violation within five years), up to $500, or a flat $1,000 for the listed serious acts.

1.3 Indiana Recordkeeping, Insurance & Enforcement

Quick Summary: Indiana law mandates rigorous operational compliance under 355 IAC 4-4-1 and IC 15-16-5. Commercial applicators must record 13 specific data elements for every Restricted-Use Pesticide (RUP) application, complete the record by the thirtieth day from the application date, and retain it for two (2) years. Businesses must carry proof of financial responsibility — OISC's published minimum is $300,000 general liability as a combined single limit. The Office of Indiana State Chemist (OISC) enforces compliance through inspections, sample analyses, stop-sale orders, and the severity-graded civil penalty tiers in IC 15-16-5-66 ($250 / $500 / $1,000).


Indiana Commercial Recordkeeping Mandates (355 IAC 4-4-1)

Accurate, timely recordkeeping is both a vital regulatory requirement and an applicator's primary legal defense in the event of off-target drift allegations, non-target crop injury, or chemical exposure complaints. Under 355 IAC 4-4-1, commercial applicators must keep records of every application of a restricted use pesticide. Certain commercial applicators — including public applicators, not-for-hire applicators, and Category 7b termite operators — must also keep records of general use pesticide applications.

The 13 Mandatory Recordkeeping Elements

No specific form is required, and records may be kept on paper or electronically. Every record must include:

#Required element
1Name of the customer, property owner, or custodian of the site of application.
2Address, geographic coordinates, or general location description of the site of application.
3Name of the person making the application.
4Name of the commercial or private applicator responsible for the application, if different from #3.
5License number of the responsible commercial or private applicator.
6Date of application.
7Start and stop times of the application.
8Description of the plants, crop, animals, commodities, stored products, or sites treated.
9Principal pests to be controlled.
10Specific acreage, area, parts of the structure, parts of the property, or number of plants or animals treated, or other appropriate description.
11Brand name of each pesticide product applied.
12EPA registration number of each pesticide product applied.
13Amount of each product used, expressed as either the total quantity/volume of the packaged product, or of the diluted mixture plus the active ingredient concentration (percentage).

[!WARNING] Five things Indiana does not require in this record. Application rate, carrier volume, air temperature, wind speed, and wind direction are absent from 355 IAC 4-4-1. Those appear in other states' rules (Missouri's 2 CSR 70-25.120(4) requires measured wind, for example) and in label-directed recordkeeping for specific products such as dicamba over-the-top soybean and cotton herbicides, where the label demands far more detail than the state rule. Read the label for every new purchase — label-directed records can change without notice.

Extra Records for Termite Work (355 IAC 4-4-1(d))

For for-hire termite control, the record must also include a copy of the contract or service agreement, a graph or diagram of the treated structure, the dimensions of the structure (including depth from grade to the top of the foundation footing when soil-applied liquids are used), the treatment specifications for soil-applied liquids, and a signed copy of the termite control customer disclosure form where applicable.

Record Retention & Inspection Accessibility

  • Creation deadline: The record must be created by the thirtieth day from the date of application.
  • Mandatory retention: At least two (2) full years from the date of application, written or electronic.
  • OISC availability: The State Chemist must be provided access to the records (IC 15-16-5-59(c)).
  • Customer copies: If requested, the commercial applicator must provide a copy of the record to the person for whom the pesticide was applied within thirty (30) days of the application date, and that person must keep the copy for two years.

Financial Responsibility Requirements (IC 15-16-5-58)

To protect the public from financial loss resulting from negligent pesticide drift, chemical misapplications, property damage, or bodily injury, Indiana statute requires every licensed Pesticide Business to establish and maintain proof of financial responsibility.

+-----------------------------------------------------------------------------------------+
|          Financial Responsibility — What the Statute Requires vs. What OISC Sets        |
+-----------------------------------------------------------------------------------------+
|  IC 15-16-5-58:           A surety bond, a certificate of liability insurance in force, |
|                           or a certificate of financial responsibility. The statute     |
|                           itself names NO dollar figure.                                |

Insurance Compliance Provisions

  • Certificate of Insurance: Proof must be provided by the issuing insurance company on a certificate of insurance, issued in the name of the business printed on the license, and re-filed whenever the proof on file expires. The State Chemist may be listed as a certificate holder.
  • Continuous Coverage: IC 15-16-5-58(a) is blunt about the consequence of a lapse — if the bond, insurance, or financial responsibility is not maintained at all times during the licensing period, the business license, the pest inspector license, and every associated commercial applicator license and technician registration are invalid. The business may not operate until financial responsibility is back in compliance and the State Chemist reinstates the license.
  • No liability shield: IC 15-16-5-58(b) makes clear that complying with the chapter does not relieve anyone of liability for damage caused by pesticide use, even when the use conformed to the rules.

OISC Regulatory Enforcement Powers

The Office of Indiana State Chemist possesses broad statutory authority under IC 15-16-4 and IC 15-16-5 to enforce pesticide compliance throughout Indiana.

Investigative Protocols

  1. Routine Audits: OISC field investigators perform unannounced audits of commercial business facilities, reviewing storage containment, mixing/loading pads, supervision training records, and 13-element application records.
  2. Drift & Complaint Investigations: When off-target drift or crop damage is reported, OISC investigators visit the incident site, document symptomology, collect vegetative and soil samples, record weather data, inspect application equipment, and establish strict chain-of-custody for state laboratory residue testing.
  3. Stop-Sale, Use, or Removal Orders: The State Chemist can issue immediate administrative "Stop-Sale" orders prohibiting the movement, distribution, or application of unregistered, adulterated, or misbranded pesticide products.

Civil Penalty Structure & Criminal Sanctions (IC 15-16-5-65, -66, -70)

Indiana's civil penalties are set by statute, not by an administrative penalty schedule, and they are graded by how serious the act was, not by how many prior offenses the applicator has. This is the single most commonly misstated fact about Indiana pesticide enforcement.

+-----------------------------------------------------------------------------------------+
|                     OISC Civil Penalty Tiers (IC 15-16-5-66)                            |
+-----------------------------------------------------------------------------------------+
|  Up to $250    General violation of the chapter or a rule. May be imposed ONLY if a     |
|                warning for the SAME violation was previously issued to that person      |
|                within the previous FIVE (5) years. Adjustable for mitigation.           |
|                                                                                         |
|  Up to $500    Neglecting, after written notice, to keep records or supply information; |
|                false records or reports; UNKNOWINGLY operating for hire without a       |
|                business license or letting an uncertified person apply; misuse of a     |
|                NON-restricted product causing an adverse effect; drift of a             |
|                non-restricted pesticide causing an adverse effect. Adjustable.          |
|                                                                                         |
|  $1,000 flat   REFUSING to keep records or supply information; operating in a careless  |
|                or negligent manner; refusing to comply after notice; KNOWINGLY          |
|                operating without a license; fraud in a license application; misuse of a |
|                RESTRICTED use pesticide causing an adverse effect; RUP drift causing an |
|                adverse effect. NOT adjustable for mitigation.                           |
+-----------------------------------------------------------------------------------------+

Mitigation — the 20% Rule

For the $250 and $500 tiers only, the State Chemist may reduce the penalty by 20% for each of three mitigating actions: cooperating with the investigation, taking corrective action to prevent recurrence, and compensating a victim for adverse effects. Penalties in the $1,000 tier may not be adjusted.

The Nineteen Grounds for Action (IC 15-16-5-65)

Section 65 lists the acts that expose a licensee to a warning, citation, civil penalty, or denial/suspension/revocation/modification of any license, permit, registration, or certification. High-frequency exam items include: using a product inconsistent with its labeling; operating faulty or unsafe equipment; operating in a careless or negligent manner; refusing to keep records; making false records; operating for hire without a business license; letting an uncertified person apply a product that requires certification; failing to maintain financial responsibility; and impeding the State Chemist.

Where the Money Goes and How to Appeal

Civil penalty money collected under section 65 is credited to Purdue Pesticide Programs and may be used only for pesticide education. A person aggrieved by a State Chemist decision may obtain review by the Indiana Pesticide Review Board by filing a written petition within thirty (30) days of the decision (IC 15-16-5-67).

Criminal Sanctions (IC 15-16-5-70)

  • Class C misdemeanor: recklessly, knowingly, or intentionally violating the chapter, or impeding or preventing the State Chemist or the State Chemist's agent from performing a duty.
  • Class A misdemeanor: recklessly, knowingly, or intentionally operating for hire without a business license (section 65(9)) after the State Chemist has issued written notification about a previous violation of that same provision.

[!CAUTION] Do not memorize a "first offense $250 / second $500 / third $1,000" ladder for Indiana. No such rolling three-year schedule exists in 355 IAC 4 or in IC 15-16-5. The $250 tier is the least serious tier and requires a prior warning for the same violation within five years before any money can be assessed; $500 and $1,000 attach to specific enumerated acts, principally turning on whether conduct was unknowing versus knowing and whether the product was general use or restricted use.
