Table 1: Extremely Hazardous Substances, Threshold Planning Quantities, and Reportable Quantities

The following table lists the most commonly used pesticides on the EPA's list of Extremely Hazadrous Substances (EHS) and their Threshold Planning Quantities (TPQ).

IF YOU HAVE FORMULATIONS OF THE EXTREMELY HAZARDOUS SUBSTANCES (EHS) THAT DO NOT APPEAR IN TABLE 1, RECORD THESE FORMULATIONS ON THE CHEMICAL INFORMATION FORM FOUND IN THE EXTENSION BULLETIN #E-2575 FOR VERIFICATION BY THE LOCAL EMERGENCY PLANNING COMMITTEE (LEPC).

PRODUCT NAME (FORMULATION)

This list is alphabetical by the product's trade or brand name.

CHEMICAL NAME (EHS) (active ingredient)

This is the chemical name of the Extremely Hazardous Substance (EHS) in the product.

PRODUCT THRESHOLD PLANNING QUANTITY (TPQ)

Quantities in this column were calculated for the product as purchased, given that usually only a percentage of the product is an Extremely Hazardous Substance (EHS). Therefore, the farm must have the amount of product listed in this column on hand or expects to have it on hand in the coming year for the farm to be subject to the reporting and planning requirements.

PRODUCT REPORTABLE QUANTITY (RQ): FOR SPILL OR RELEASE

If the quantity in this column (or a greater amount) is spilled or released, it must be reported immediately to the Local Emergency Planning Committee (LEPC), the Pollution Center (telephone numbers are located on the information source page. A written follow-up report must also be submitted (see Form A, Emergency Notification Form of Extension Bulletin #E-2575). Routine agricultural application of these products is not considered a spill or release. (See Fact Sheet).
NOTE: Several products in the table are discontinued or cancelled (indicated by ¹). If you have any of these discontinued or cancelled products, contact your LEPC for direction. There may also be other product names or formulations of the Extremely Hazardous Substance (EHS) that have not been included in Table 1 or Table 2. If these products are being stored and their active ingredient(s) are listed in Table 1, the products should be included on the Chemical Information Form.
