- (a) The requirements of Sections R315-265-440 through R315-265-445 apply to owners and operators of facilities that use new or existing drip pads to convey treated wood drippage, precipitation, and surface water run-off or any combination of the three to an associated collection system. Existing drip pads are those constructed before December 6, 1990 and those that the owner or operator has a design and has entered into binding financial or other agreements for construction before December 6, 1990. Any other drip pads are new drip pads. The requirement at Subsection R315-265-443(b)(3) to install a leak collection system applies only to those drip pads that are constructed after December 24, 1992 except for those constructed after December 24, 1992 that the owner or operator has a design and has entered into binding financial or other agreements for construction before December 24, 1992.
- (b) The owner or operator of any drip pad that is inside or under a structure that provides protection from precipitation so that neither run-off nor run-on is generated is not subject to Subsection R315-265-443(e) or R315-265-443(f), as appropriate.
- (c) The requirements of Sections R315-265-440 through R315-265-445 are not applicable to the management of infrequent and incidental drippage in storage yards if:
(1) the owner or operator maintains and complies with a written contingency plan that describes how the owner or operator will respond immediately to the discharge of the infrequent and incidental drippage. At a minimum, the contingency plan shall describe how the facility will do the following:
(i) clean up the drippage;
- (ii) document the cleanup of the drippage;
- (iii) keep documents regarding cleanup for three years; and
- (iv) manage the contaminated media in a manner consistent with Title R315.
