Mich. Admin. Code R. 285.640.4 - Primary containment of bulk liquid pesticides

Rule 4.

(1) A storage container shall not be made of ferrous metals unless the container is made of stainless steel, the container has a protective lining which prevents corrosion and which does not react chemically with the stored pesticide, or the manufacturer of the stored pesticide has confirmed, in writing, to the department that corrosion tests have been conducted and storage in such unlined containers has been found to be satisfactory.

(2) Storage containers and appurtenances shall be constructed of materials that are resistant to corrosion, puncture, and cracking.

(3) Metals that are used for valves, fittings, and repairs on metal containers shall be compatible with the metals that are used in the construction of the storage container so that the combination of metals does not cause or increase corrosion which may weaken the storage container or its appurtenances or create a risk of discharge.

(4) Storage containers and appurtenances shall be designed to handle all operating stresses, taking into account static head, pressure buildup from pumps and compressors, and any other mechanical stresses to which the storage containers and appurtenances may be subject in the course of operations.

(5) Storage containers and appurtenances, including pipes, shall be protected against reasonably foreseeable risks of damage by trucks and other moving vehicles that are engaged in the handling of a bulk pesticide.

(6) All wetted parts inside shutoff valves and connections from the storage container to the shutoff valve shall be made of stainless steel or other material that is approved by the department. Minibulk pesticide containers that are in compliance with DOT-57 or MACA-75 specifications are exempt from the provisions of this subrule.

(7) Provision shall be made to prevent cross-contamination due to the use of common metering or plumbing devices.

(8) Storage containers shall not be filled to more than 95% of capacity unless any of the following provisions apply:

(a) The storage container construction or location provides constant temperature control.

(b) The storage container is a minibulk pesticide container.

(c) The storage container is otherwise designed to be filled to a capacity of more than 95% of its total volume according to the manufacturer's recommendations.

(9) Flexible connections and properly supported appurtenances shall be utilized as dictated by engineering practices to reduce vibrational and stress-related deterioration.

(10) Backflow protection or a fixed air gap shall be utilized to protect water lines as required by standard engineering and plumbing practices.

(11) Primary containment piping shall be located above the ground and within secondary containment.

(12) Storage containers shall be anchored, elevated, or secured by some other means to prevent flotation or instability.

(13) Mobile storage containers that contain liquid pesticide shall be stored not less than 100 feet from a water well or surface water or as required by the pesticide label, whichever distance is greater.

(14) A person shall not store liquid pesticide in an underground storage container. This prohibition does not apply to a watertight catch basin or sump that is used for the temporary collection of runoff or rinsate from transfer and loading areas.

(15) Storage containers which are located outdoors and which are more than 10 feet in height shall be placed a minimum of 5 feet from the secondary containment wall or, as an alternative, shall be designed to prevent liquid pesticide discharges from the storage container over the side of the dike wall. The distance between containers shall be adequate to allow for inspection and maintenance.

(16) Facilities that have existing secondary containment areas on the effective date of this rule are exempt from the wall setback and design requirements specified in subrule (15) of this rule. The distance between containers shall be adequate to allow for inspection and maintenance.

(17) Storage containers which are located within a walled structure and which are lower than the surrounding walls are exempt from the wall setback and design requirements specified in subrule (15) of this rule. The distance between containers shall be adequate to allow for inspection and maintenance.

(18) All bulk pesticide containers shall be labeled in accordance with the provisions of Act No. 171 of the Public Acts of 1976, as amended, being S286.551 et seq. of the Michigan Compiled Laws, and the federal insecticide, fungicide, and rodenticide act of 1988, as amended, 7 U.S.C.S136 et seq. The registered product label shall be affixed in a prominent location on the bulk pesticide storage container and shall be designed to remain intact and legible throughout the active use of the container.

(19) Facilities that are placed in service after the effective date of this rule shall immediately comply with this rule. Facilities that are in service before the effective date of this rule shall have 1 year to comply with this rule.
