Spill and Discharge Procedure

All spill responses at MSP should follow the guidelines established in the Minneapolis/St. Paul International Airport MAC/Tenant Integrated Spill Response and Coordination Plan. Contact MAC Environment for a copy of the plan. The following guideline has been prepared to help construction projects understand and implement those requirements. When a spill or discharge occurs at the project site, there are three primary goals:

1. Containment
2. Cleanup
3. Reporting

1. Containment

As soon as the area is safe for entry, containment operations should commence. The extent of the response depends on the nature of the release, but typical response actions could include: 

Placing adsorbent materials to capture pooled liquid 

• Berming to contain and prevent further migration of the liquid 
• If the spill affects surface water near a sump, immediately cease dewatering 
• If the spill affects surface water near a sump, ditch, or low-lying area place booms or take other actions to capture and contain liquid.

2. Clean-up 

• As soon as the area is safe for entry, clean-up operations should commence.  
• In situations where a small volume of petroleum is released to soils, the clean-up operations will include excavation and containerization of the impacted soils.  
• The MAC's target is to commence clean- up operations for the affected soils within 30 minutes of discovering the spill or discharge event.  

3. Reporting 

If the spill or discharge is reportable, an immediate report must be made to MAC Communications. Nothing precludes the responsible party from also calling the State Duty Officer; however, the MAC's target is to report all such incidents to the SDO within 15 minutes.  

A spill or discharge incident is reportable if any of the following conditions are true: 

• The material that is spilled or discharged is not a petroleum product; or 
• The volume that is spilled or discharged is 3 gallons or more (if there is any question as to whether it exceeded the 3-gallon threshold, the spill must be reported); or 
• The material that is spilled or discharged is not being contained and has contacted (or will contact) standing or flowing water leading to one or more dewatering sump or storm drains. 

If any of the conditions above are true, you must contact MAC Communications immediately. To the best of your ability, please have the following information available: 

• Date, Time, and Location of spill/discharge 
• Phone number for call-backs at the scene 
• Responsible party if known 
• Is release on-going, is clean-up occurring? 
• Estimate of volume spilled/discharged 
• Type of material spilled/discharged 
• Did the release reach storm sewers? 
• Is MAC Fire required on scene for safety? 

The construction general contractor and MAC’s Environmental Consultant should also be contacted (after MAC Communications has been notified). 

4. Field Personnel - Responsibilities 

All spill and discharge incidents must be reported to both the project general contractor and MAC’s environmental consultant. The person that noted the incident is responsible for relaying information to the project general contractor. 

• If an incident is reportable to MAC Communications as indicated above in the "Reporting" section, the discovering party shall report it immediately. 
• If there is a substantial release, and you do not have the ability to provide containment of the spill or discharge, call MAC Communications. MAC Communications will initiate emergency response actions. 
• If the spill or discharge is migrating toward any sump, the sump must be shut down immediately. 
• Field personnel are expected to be aware of the location of containment and clean-up equipment maintained on-site by the general contractor. 
• Field personnel shall serve as the on-site contact for spills/discharges until appropriate party has assumed responsibility. 

5. Project General Contractor - Responsibilities 

The project general contractor will relay information related to the spill or discharge event to MAC’s Environmental Consultant and will be responsible for coordinating the clean-up actions. The clean- up actions should commence within 30 minutes of discovery of the spill or discharge incident. 

• The project general contractor must confirm the discovering party has contacted MAC Communications for all reportable spills/discharges. 
• The project general contractor must confirm the Liesch project manager has been notified of any spill or discharge and that adequate containment, clean-up, and disposal has occurred. 
• The project general contractor will maintain on- site and readily available to field personnel an adequate supply of response equipment that should include absorbent pads, skimmer booms, gloves, goggles, shovel(s), and other appropriate materials for use in containing spills and discharges. 

The project general contractor will maintain, at the ready, an appropriate on-site container to temporarily store impacted materials collected during clean-up activities and properly dispose of these materials as appropriate.
