1 o INTRODUCTION
The purpose of the Storm Water Pollution Prevention Man is to eliminate any unnecessary contact between
storm water and materials. If contact cannot be prevented then means of control are provided. Storm water
discharges must be free of pollutants. This plan is designed to meet the requirements of the facility's NPDES
General Storm Water Permit.
2. S I'T MAP
Map #1 identifies:
significant material storage areas.
facility structures,
pervious impervious areas,
discharge outfalls,
direction of storm water runoff,
drainage areas,
BMP locations
3. DESCRIPTION OF POTENMAL POLLUTANTS
Table 1. identifies all significant materials stored, handled, managed, processed, fabricated, manufactured,
transported, or transferred at the facility. The drainage area for the material is described. An ID number is
given to those materials exposed or if their storage container is exposed to precipitation. The ID number is
used in other sections to correlate the material with storage areas. Refer to Table 2 for existing controls in
place to prevent storm water contamination for exposed materials.
4. LOCATION INVENTORY BEST MANAGEMENT PRACTICES
Each of the items with an ID number in Table 1 is given a page that identifies best management practices,
either non-structural and structural controls to further help prevent storm water contamination. This section
includes controls already in place.
Best management practices will be amended when needed. If spills or other areas of concerns are identified,
more best management practices will be included to address each situation.
5. DRAINAGE DISCHARGE SUMMARY
Discharges from the site have been examined for the presence of non storm water discharges. Based upon a
review of current site drawings, and a visual inspection of the discharges there are no non-storm water
discharges.
6. MAINTENANCE PROGRAM
Storm water management is an important aspect of the facility's solid waste permit. Construction and
maintenance of storm water controls have been incorporated site development plans and addressed in the
Facility Operations Manual.

7. SPILL PREVENTION RESPONSE PROCEDURES
There is no permanent storage of bulk chemicals or petroleum products on site. Landfill operators have
been trained to notify NSP's emergency responder (EIRC) if a spill occurs. The ERIC responder will
direct facility staff on the necessary clean up procedures. Complete documentation of spill response
procedures are included in the Operators Manual Vol 1.
8. EMPLOYEE TR AmaNG
Work at the landfill is performed under the direction of a licensed operator. License operators receive
general training each year. Storm water training, specific to the facility, will be conducted at the facility
one year after permit issuance. A refresher course will be presented approximately 3 years later.
9. KEY RESPONSIBILITIES
Management is responsible for the following:
O approval and implementation of the Storm Water Pollution Prevention Plan,
ensuring the Storm Water Pollution Prevention Plan is reviewed at least once annually,
ensuring that this plan is revised whenever there is a change in materials or materials
O ensuring that the plan is revised whenever it is determined that the plan is not controlling the
discharge of pollutants in storm water.
certifying that discharges from the site have been evaluated for the presence of non storm water
discharges and that no non storm water discharges from the site exist not covered by an NPDES
permit.
ensure that facility personnel have an adequate understanding of the Storm Water Pollution
Prevention Plan and the NPDES General Storm Water Permit.
6 identify the personnel that will be responsible for managing this Storm Water Pollution Prevention
O Plan, implementation, and reporting requirements. These persons shall be available at reasonable
times of operation. Contingencies will be provided so that unanticipated absences do not prevent
adequate management of the plan.
RESPONSIBLE INDIVIDUALS:
Management responsible for meeting plan and permit requirements:
Tom Thomsen (612) 731 5703
Plant Manager
Responsible for inspections, documentation and regulatory requirements:
Chuck Donkeys (primary) (612) 330 -6082
Env Analyst
10. INSPECTIONS AND DOCUMENTATION
At least once every two months the site shall be inspected. Inspections should be preformed in April,
June, August and October of each year. The inspection shall be conducted for the purpose of determining
the maintenance of structural and non structural storm water management practices. At least one
inspections shall be conducted while storm water is discharging from the site. The inspection report form
shall be fully completed.
The following items will be inspected and documented where appropriate:
1. evaluate the facility to-determine if the Plan accurately reflects site conditions... document any
inaccuracies.
2. evaluate the facility to determine whether new exposed materials have been added to the site.
3. during the inspection when run off is occurring, observe if it is discolored or contaminated.
4. determine if structural and non structural BMPS are functioning properly.
Inspection forms and annual reports shall be attached to this storm water pollution prevention plan. These
three items and any plan amendments are the only documentation requirements for this plan.
