· Communicate, any releases observed during unloading or transfer and completion of unloading or transfer of all bulk chemicals with the Control Room and as described in the Spill Plan.

· Communicate to the driver to maintain constant supervision on all equipment associated with the bulk chemical being delivered or transferred.

· Monitor for leaks and visible or fugitive emissions from bin vent filter, top of silo pressure relief valve or access hatch during filling.

INITIAL ACTIONS

|_|1. Verify chemical’s identity on the Bill of Lading match receiving tank or silo and that delivery was scheduled

· For DOT Hazardous material look for DOT shipping name, marking, labels/placard and condition of truck

· Proper DOT shipping paper will have the following contents:

· Carrier, Receiver (Consignee) and Shipper (Consignor) information

· Description of the article being shipped and amount. An “X” or “RQ” will be in “HM column”

· Bulk containers have placards on each side and each end with ID# (UN/NA). Only each side if < 1000 gal |_|2. Review/follow procedures and PPE as defined by safety requirements for the bulk chemical being unloaded |_|3. Verify tank/silo has adequate capacity for the amount of chemical being delivered and review any fill rate or capacity restrictions with driver. Enter tank or silo available capacity: _________________________ |_|4. Backing trucks must have an operable reverse alarm-or spotter |_|5. Verify truck brakes are set and wheels are chocked

BEFORE UNLOADING

|_|1. Secure area with caution tape/barriers and test/check safety shower/eye wash-review operation with driver |_|2. Per Spill Plan, place signage or other means to warn others of the transfer operation |_|3. Contact Control Room and get permission to unlock connections, if required |_|4. For lime unloading, obtain sample for the periodic reactivity test, per facility specific requirements |_|5. If unloading using plant air, drain condensed water from airline prior to making connection |_|6. Verify all valves have been correctly aligned in proper sequence for the unloading operation |_|7. Ensure those working within the secured unloading area are wearing required unloading PPE (City employees: City required PPE. Driver/helper: vendor/transporter required PPE with at least the minimum City required PPE)

SPILL PREVENTION

|_|1. Inspect all truck ports/drains for leakage. If leaks are found, contact the Control Room immediately |_|2. Place clean (5-gal. minimum) plastic pail under each truck transfer line connection prior to unloading; typically not required for delivery of diesel from hose reel |_|3. Ensure proper containment is set up for tank relief lines or other potential overflow points (e.g., prevent spills from entering environment or u-drain) |_|4. Place spill response matting over storm drains per the Spill Plan |_|5. Verify hoses and couplings are in good operating condition |_|6. Verify secure truck-to-piping/tank or silo connections (cam-lock fittings secured with pins, tape, etc) |_|7. Verify spill kit cleanup materials (absorbents, neutralizers) are available as identified in the Spill Plan |_|8. Identify level gauge(s) to watch during unloading to prevent exceeding fill limit or tank/silo capacity

ATTENDING UNLOADING

|_|1. Attend each unloading operation from beginning to end. If facility approved, after connections and set-up has been verified, Carbon, Dry Pebble/Hydrated Lime and Urea may be unloaded by the driver - unattended by a City employee |_|2. If unloading is unattended, inform driver of the location of communication device and method used to contact the Control Room upon completion of unloading, emergency situation, spill, or equipment failure |_|3. Inform driver to notify Control Room upon completion of unloading and wait for a City employee to come to the area of unloading before disconnecting any lines

DURING UNLOADING

|_|1. Driver and anyone attending must watch for leaks/fugitive emissions from bin-vent filter, top of silo pressure relief valve, level gauge, hatches and equipment failures. STOP unloading immediately upon observation of a spill, visible emission, equipment failure or high-level alarm or any other high-level indication |_|2. Report any releases to the Control Room/Shift Supervisor immediately and respond to any releases that occur as directed by the Spill Plan

AFTER UNLOADING

|_|1. Blow/drain residual bulk chemical left in transfer lines-confirm that lines are not pressurized |_|2. Verify all valves have been correctly aligned in proper sequence for disconnection |_|3. Disconnect truck-to-piping/storage container connections and catch any residual in pails. Re-use acceptable chemical in the process it was intended |_|4. Inspect all truck ports and drains for leakage. If leaks are found, contact the Control Room immediately - leaks must be stopped before the truck leaves the site |_|5. Restore area to pre-unloading condition - Properly stow all equipment. Secure filling pipe cap and lock it as applicable |_|6. Sign shipping papers only after properly receiving the material.
