Pesticide General Permit Decision Tool

DEC developed an interactive decision tool to help you answer the following questions about the Alaska Pollutant Discharge Elimination System (APDES) Pesticide General Permit (PGP):

  • Do I need an APDES permit for my pesticide applications?
  • Am I eligible for coverage under the APDES PGP?
  • What is required of me under the APDES PGP?

NOTE: This is an interactive tool for your informational purposes only. The information in this step-by-step guide is based on DEC’s 2017 APDES PGP and is only to be used for areas where DEC is the APDES permitting authority (the State of Alaska - except lands within the Metlakatla Indian Reservation and the Denali National Park Reserve).

Step 2: I need an APDES permit for my pesticide application in the State of Alaska. Am I eligible for coverage under DEC's APDES Pesticide General Permit (PGP)?

You are not eligible for coverage under DECs APDES Pesticide General Permit (PGP). You may be eligible for coverage under EPA's NPDES Pesticide General Permit. See www.epa.gov/npdes/pesticide-permitting/ for more information.

You are not eligible for coverage under DECs APDES Pesticide General Permit (PGP).
You should contact the APDES Stormwater and Wetlands Program for more information (907-334-2288).

You are eligible for coverage under DEC's APDES Pesticide General Permit (PGP). (See Part 1.1 of the permit for further eligibility details).


Step 3: I need an APDES permit for my pesticide application and I am eligible for coverage under DEC's APDES Pesticide General Permit (PGP). What is required of me under the PGP?


Are you a decision-maker or a for-hire applicator? (See Part 1.0 and Appendix C for definitions.)

  • Decision Maker: Any entity with control over the decision to perform pesticide applications including the ability to modify those decisions that result in a discharge to waters of the United States.
  • Applicator: Any entity who performs the application of a pesticide or who has day-to-day control of the application (i.e., they are authorized to direct workers to carry out those activities) that results in a discharge to waters of the United States.

Will any of your discharges be to waters of the U.S. containing Federally Listed Essential Endangered and Threatened Species or Designated Critical Habitat (Listed)?

Listings of endangered and threatened species and federally-listed critical habitat in Alaska and interactive maps is available at:


Are you a federal or state agency with the responsibility:

  1. to control mosquitoes for public health, nuisance control or animal welfare;
  2. to control weeds and algae;
  3. to control animals for public health, nuisance control or resource management; or
  4. to control forest canopy pests?

Are you a:

  1. mosquito control district or similar pest control district; or
  2. irrigation and weed control district or similar pest control district?

Are you a small entity as defined in Appendix C of the permit?

A small entity is any:
  1. private enterprise that does not exceed the Small Business Administration size standard as identified at 13 CFR 121.201, //www.sba.gov/federal-contracting/contracting-guide/size-standards/ , or

Will you exceed any of these thresholds?:
(For calculating annual treatment area thresholds , see the definition in Appendix C of the permit.) (PDF)

  1. adulticiding more than 6,400 acres during a calendar year;
  2. weeds or algae pest control with an annual treatment area of more than either 20 linear miles or 80 acres;
  3. animal pest control with an annual treatment area of more than either 20 linear miles or 80 acres;
  4. treating more than 6,400 acres of forest canopy pests during a calendar year; or
  5. treating a Tier 3 water to restore or maintain water quality or to protect public health or the environment that either does not degrade water quality or only degrades water quality on a short-term or temporary basis?
