11.1 Supervising Noncertified Applicators & Employer Duties

11.1 Supervising Noncertified Applicators & Employer Duties

Federal core competency area 40 CFR § 171.103(c)(9) is titled Responsibilities of Supervisors, and it exists because most restricted-use pesticide is not applied by the person whose name is on the certificate. It is applied by employees working under that person's authority. The certification system holds the certified applicator accountable for what those employees do.

Who May Apply a Restricted-Use Pesticide

The rule from Section 2.3, restated as a supervision question: a restricted-use pesticide may be purchased, used, or applied only by a certified applicator, or by a person acting under the direct supervision of a certified applicator, and only for uses covered by that applicator's certification categories.

Two consequences follow immediately:

1. Category match is not optional. A commercial applicator certified only in Category 3A (Ornamental & Turf Pests) cannot supervise a restricted-use application in Category 1A (Agricultural Pests). The supervisor's certification defines the boundary of what the crew may lawfully do.
2. The supervisor's certificate is what makes the crew's work lawful. When the supervisor's license lapses — as it does on January 31 if the renewal and four CEUs are not complete (Section 1.3) — every application made under it after that date becomes an unsupervised, unlicensed application.

Federal Requirements for the Noncertified Applicator

40 CFR § 171.201 sets the conditions a noncertified applicator must meet before using a restricted-use pesticide under direct supervision:

40 CFR § 171.201 also states what the certified applicator must ensure, and these five items are exactly the supervision checklist:

1. The noncertified applicator has access to the product labeling at all times during its use.
2. The required PPE is worn and used correctly for its intended purpose.
3. The application equipment is in proper operating condition before each day of use.
4. The noncertified applicator has a means to immediately communicate with the certified applicator.
5. The certified applicator is physically present at the site when the product labeling requires it.

The training requirement is not a formality. It covers label comprehension, PPE, exposure routes, decontamination, emergency response, and the supervisor's contact information — precisely the material in Chapters 4, 5, and 10 of this guide. Note that the training route matters as much as the training itself: an employee who completed only a Worker Protection Standard handler course is qualified through the 40 CFR § 170.501 route, while an employee trained under the EPA noncertified applicator program must have that training within the last 12 months.

What "Direct Supervision" Actually Requires

Direct supervision is a legal standard, and its content shifts depending on what the label says.

The Default Standard

Unless the labeling says otherwise, the certified applicator does not have to be physically present at the moment of application. The applicator must:

• give specific, job-relevant instructions — the product, the site, the rate, the target, the hazards, and the restrictions;
• ensure the required PPE is available and in serviceable condition;
• ensure decontamination supplies and clean water are on site;
• ensure the equipment is calibrated and functional;
• remain available — reachable by cellular telephone or two-way radio and within a reasonable response distance;
• verify that the noncertified applicator meets the age, training, and label-comprehension requirements above.

The Label Override

Some labels — soil fumigants, structural fumigants, and certain high-hazard restricted-use products — state that the certified applicator must be physically present at the site during application, tarp sealing, or aeration. That is mandatory label language. When a label requires physical presence, being reachable by phone is a FIFRA Section 12(a)(2)(G) violation, not a judgment call. In New Mexico, fumigation is separately certified as Category 7C precisely because the hazard warrants that level of control.

The New Mexico Overlay: Commercial Operator / Technician

New Mexico adds a licensing layer on top of the federal supervision standard, and the details are testable:

• An employee of a Commercial Applicator who applies any pesticide — general-use included — is a Commercial Operator / Technician and must be licensed in that capacity.
• The operator/technician application form must be acknowledged by the employing Commercial Applicator. The employment relationship is part of the licensing record.
• The operator passes the Operator exam, which covers general pesticide information and New Mexico laws and rules. As Section 1.2 established, operators do not take category exams.
• The operator/technician license fee is $75, and the same 60-day completion window from the approval date applies.
• For wood-destroying pest work (Category 7D), the operator must attend approved training and pass a Wood Destroying Pest Control exam, and must maintain the additional four category-specific CEUs each year.
• The operator carries the same annual renewal and four-CEU obligation described in Section 1.3.

Distinguish the two regimes. Federal law asks whether a person may handle a restricted-use pesticide under supervision. New Mexico law asks whether a person applying any pesticide for a commercial applicator holds an operator/technician license. A crew member can satisfy the federal noncertified-applicator training rule and still be operating illegally in New Mexico without the operator license.

The Employer's Separate Duties

Where the site is an agricultural establishment producing agricultural plants, the Worker Protection Standard (40 CFR Part 170) from Section 5.3 imposes handler-employer duties in parallel with the supervision rules: annual handler training, PPE provision and maintenance, decontamination supplies, application-specific information, and the safety poster and central display. A commercial applicator working on someone else's farm does not escape these obligations — Section 5.3 covered the information exchange each party owes the other.

Recordkeeping and Liability

21.17.50.10 NMAC requires the application record to name the applicator and license number. That field is the accountability hinge: the record must show who actually applied the product and under whose license the application was made.

The liability point is the one candidates most often underestimate:

• The certified applicator bears legal responsibility for misapplication, drift, Worker Protection Standard violations, and environmental damage caused by people working under their supervision. Delegating the work does not delegate the responsibility.
• NMSA 1978, Section 76-4-23 lists, among the grounds for denial, suspension, or revocation, applying pesticides without proper supervision and aiding an unlicensed person in evading the Act. Both are supervision failures on the certified applicator's part.
• NMSA 1978, Section 76-4-24(C) is blunt about civil exposure: nothing in the Pesticide Control Act "shall be construed to relieve any person from liability for any damage to the person or lands of another caused by the use of pesticides, even though such use conforms to the rules and regulations of the board." Perfect regulatory compliance is not a defence to a damage claim.
