Sec. 1.
(a) Operational areas at a storage facility for bulk and minibulk containers shall have containment that is curbed and paved with reinforced concrete or other approved material that provides an impervious surface. Operational area activities shall be carried out within this containment.(b) The operational area containment shall be constructed and reinforced to support the foreseeable maximum gross load of all product, equipment, and motor vehicles utilizing the area. The containment shall have a minimum width of ten (10) feet, a minimum length of twenty (20) feet, and a minimum capacity of seven hundred fifty (750) gallons. Points of loading and unloading shall be positioned over the containment.(c) Wherever sufficient capacity required in 355 IAC 5-4-1(c) and provisions of this rule are complied with, the secondary containment described in 355 IAC 5-4 may be designed for and jointly used in lieu of a separate operational area containment.(d) The operational area containment shall form or drain into a watertight catch basin. If the operational area containment drains to a sump, the catch basin may include the sump and an aboveground container, provided a pump is installed which automatically transfers the contents of the sump into an aboveground container. Containers used for the temporary storage of liquids collected from the operational area containment shall be located within secondary containment.(e) All liquids shall be promptly removed from the operational area containment for use in the blending process or for proper disposal in accordance with all applicable rules. The capacity required in subsection (b) shall be available at all times.(f) Storage containers and appurtenances shall be protected against reasonably foreseeable risks of damage by vehicles operating in the area.(g) This section does not apply to the unloading of mobile containers at the pesticide application site. (h) Operational area containment shall be maintained as necessary to assure compliance with this rule.(i) Alternative means, including portable operational area containment systems, shall be permitted to serve as operational area containment systems if approved.State Chemist of the State of Indiana; 355 IAC 5-3-1; filed Mar 8, 1991, 2:45 p.m.: 14 IR 1405, eff sixty 60 days after filing with secretary of state; readopted filed Nov 21, 2001, 10:17 a.m.: 25 IR 1269; filed Feb 20, 2002, 9:38 a.m.: 25 IR 2216; readopted filed Sep 3, 2008, 1:46 p.m.: 20080924-IR-355080553RFAReadopted filed 10/17/2014, 9:26 a.m.: 20141112-IR-355140342RFAReadopted filed 10/26/2020, 10:27 a.m.: 20201125-IR-355200459RFAFiled 4/24/2023, 10:38 a.m.: 20230524-IR-355220386FRA
