Additional Best Management Practices. Xxxxxxxx XxXxxx shall implement the following best management practices (“BMPs”) to improve the storm water pollution prevention measures at the drop inlets and outfalls at the Facility as soon after the Effective Date of this AGREEMENT as is practicable, and no later than thirty (30) calendar days of the District Court’s entry of the Dismissal described in Paragraph 2 of this AGREEMENT:
x. Xxxxxxxx XxXxxx shall eliminate the ditch along the eastern side of the Facility in the area near 0xx Xxxxxx and D Street.
x. Xxxxxxxx XxXxxx shall expand the berm and ditch BMP alongside the western edge of the Facility adjacent to Highway 65 so as to prevent any storm water from exiting the western side of the Facility.
x. Xxxxxxxx XxXxxx shall regrade the parking lot in the southwest corner of the facility such that storm water drainage from the parking lot flows back into the Facility into a drain where it eventually flows to outfall SP-2.
d. By November 1, 2008, Xxxxxxxx XxXxxx shall resize the storm water retention ponds at the Facility, including the settling pond, the fire pond, and the emergency settling ponds, such that the aggregate capacity of the system is sized to handle all of the storm water flows into the pond system that currently exist or that are called for by the terms of this Agreement up to a 10-year, 6-hour storm event plus 50%.
e. By November 1, 2008, all discharges from the southwest part of the Facility, currently SP-1 and SP-2, will be combined into a single SP-2 discharge point, where storm water will exit this portion of the Facility if impoundment capacity is exceeded.
f. To increase storm water management efforts at the SP-2 outfall, Xxxxxxxx XxXxxx, by October 1, 2009, shall construct and install a sand filtration or other comparable treatment system that will treat accumulated storm water prior to discharge in order to maintain containment capacity availability.
g. By October 1, 2009, Xxxxxxxx XxXxxx shall alter the drainage flow from the northeast corner and the eastern side of the Facility such that this drainage is contained within the SP-2 outfall as described above in Paragraph 6(e).
x. Xxxxxxxx XxXxxx shall remove all scrap metal from both the boneyards and the northeast portion of the Facility. Xxxxxxxx XxXxxx shall not store scrap metal in these areas.
x. Xxxxxxxx XxXxxx shall install appropriate BMPs to address storm water discharges from the front of the Facility. Upon receipt of monitoring results for storm water samples take...
Additional Best Management Practices. BLT shall implement the following best management practices (“BMPs”) to improve the storm water pollution prevention measures at the drop inlets, outfalls, and other industrial areas at the Facility:
a. By August 31, 2009, BLT shall install fabric filters and hydrocarbon strips on all drop inlets at the Facility. During each rainy season, BLT shall inspect each filter after each storm event or once a week, whichever is more frequent. If necessary, BLT will either replace each filter or remove and pressure wash each filter.
b. By August 31, 2009, BLT shall design and install for all drop inlets at the Facility either removable solid covers to prevent the accumulation of dirt, leaves, and other sediment or covers that would limit debris from entering the drain lines but still allow for water to enter the storm drain system in the chance of a summer rain event. The covers shall be placed over all drop inlets on July 1st at the end of each rainy season, subsequent to appropriate maintenance of the filters as described above. The covers shall be removed as necessary prior to the first rain event of the subsequent rainy season. The covers shall remain firmly in place while there is normal activity at the Facility.
c. By August 31, 2009, BLT shall hydro-jet the entire storm water system at the Facility to remove any contaminant-containing sediment in the drain lines. During the hydro-jet process, BLT shall ensure that no water is discharged from the Facility.
d. By August 31, 2009, to slow the flow of storm water and allow more opportunity for solids to fall out before water enters the drains, BLT shall place hay xxxxx around the drop inlets at the four drains located in the east side dirt area of the Facility. BLT shall also use hay xxxxx to create a small dam and bioswale leading to the northernmost drain in the eastern dirt area. The hay xxxxx shall be trenched and keyed into the ground.
e. By October 1, 2009, BLT shall remove some of the equipment and materials stored outside in the southeastern portion of the Facility. During each rainy season, BLT shall cover any remaining equipment and materials that are stored outside in this portion of the Facility.
Additional Best Management Practices. In the event 3.1(a)(i)-(v) are ineffective to prevent off- property transport, the person, owner, or operator shall use at least one of the following best management practices:
(i) Wet suppression: apply water to disturbed soil surfaces, backfill materials, screenings, and other dust generating operations as necessary and appropriate considering current weather conditions, and prevent water used for dust control from entering any public right-of-way, stormwater drainage facility, or watercourse.
(ii) Wind barrier: construct a fence or other type of wind barrier to prevent wind erosion of top soils.
(iii) Vegetation: plant vegetation appropriate for retaining soils or creating a wind break.
(iv) Surface roughening: stabilize an active construction area during periods of inactivity or when vegetation cannot be immediately established.
(v) Cover: install cover materials during periods of inactivity and properly anchor the cover.
Additional Best Management Practices. In the event 3.10(a)(i)-(iv) are ineffective to prevent off- property transport, the person, owner, or operator shall use at least one of the following best management practices:
(i) On-tool local exhaust ventilation: use a tool-mounted dust capture and collection system.
(ii) On-tool wet suppression: use a tool-mounted water application system.
(iii) Vacuuming: use a vacuum equipped with a HEPA filter simultaneously with cutting or grinding operations.
(iv) Wet suppression: use a water sprayer or hose simultaneously with cutting or grinding operations.
Additional Best Management Practices. In the event 3.11(a)(i)-(iii) are ineffective to prevent off- property transport, the person, owner, or operator shall use at least one of the following best management practices:

(ii) Wet suppression blasting: use one of several available methods that mix water with the abrasive media or air during blasting operations.
