CORRECTIVE ACTION DESIGN SYSTEM MONITOP-JNG WORKSHEET PETROLEUM REMEDIATION PROGRAM LEAKS1TE 1571
SHOREHAM FACILITY, MINNEAPOLIS, MN Dear Stacay:
On behalf of Soo Line Railroad company doing business as Canadian Pacific (CP) we enclose for your review the Corrective Action Design System Monitoring Worksheet for the operation of the NETrM free product removal system for the above leaksite, which is located at CP’s Shoreham Facility (Facility) in northeastMinneapolis. This system monitoring annual worksheet covers the time period from October 1, 2008 through September 30, 2009.
Please do not hesitate to contact us if you have any questions. Very truly yours,

Corrective Action Design System Monitoring Worksheet
Guidance Document 4-14
This worksheet documents ongoing system emissions and efficiency, in part to fulfill U.S. Environmental Protection Agency (EPA) requirements. Complete and submit this monitoring worksheet quarterly for the first year and annually thereafter. Submit an annual monitoring report as described in Guidance Document 4-08 Annual Monitoring Report. [Note: Minnesota Pollution Control Agency (MPCA) staff may vary the frequency of progress reporting on a site specific basis.
For several remedial technologies, you are asked to provide contaminant mass removal rates in terms of gallons/day. To aid you in calculating these values, we provide a standard equation and have calculated the gallon/kilogram (gal/kg) values for various petroleum products. Please use these values in your calculations:
Product
ag_a.!_l_l_l_l_l_l_~g
gasoline 0.37
kerosene, JP4 0.33
fuel oil #1, diesel 0.31
fuel oil #2 0.30

For all sites, attach a table showing uptime and downtime for each treatment system at the site. Include explanations for any downtime that occurred during the reporting period, and a discussion of actions taken to remedy operational problems.
This system monitoring annual worksheet covers the time period from October 1, 20081 through September 30, 2009 (the "reporting period").

Corrective Action Design Systen~nitoring Worksheet O Page 2 "~
As previously described in the Detailed Corrective Action Design submitted to MPCA on October 2, 2006, recoverable free product (i.e. > 1 inch) has been detected at Leaksite 1571 in two wells:
MVV04-193-T and MV¢-2.
Well MW04-193-T is screened across the water table, and previous bail-down testing suggested that continuous, automatic free product recovery was feasible at this location. An automated Non-aqueous Extraction Technique (NETrM) System was installed on July 18, 2006 to recover free product observed in the well. Start-up occurred on July 19, 2006. The NETrM system operated continuously2 during the reporting period with the following exceptions (see Table 1 for details):
The remedial system was shut down on November 7, 2008 when the product level in the well fell below an operable level. The system remained shut down unfil the product level sufficiently recovered for normal operation on March 23, 2009.
The system was found not operational due to a tangled belt on May 12, 2009 and was re-started on May 13, 2009 after the belt was fixed.
Well MW-2 is currently screened below the water table; therefore, the observed free product is being removed in accordance with the Detailed Corrective Action Design using manual approaches. Hand bailing of free product from MW-2 was implemented from April 2007 through July 2007, at which time a free product skimmer was installed to more effectively remove the free product. The skimmer was in operation until March 16, 2009, when it began collecting water in addition to product. As a result, absorbent socks are now being employed to recover free product. MW-2 is inspected quarterly along with other wells at the Leaksite. Product collected from MW-2 is
combined with free product collected by the NETTM system in well MW04-193-T, which is then sent
off-Site for disposal.
FREE PRODUCT RECOVERY SYSTEMS
Attach a table of free product thickness in all monitoring and recovery wells (to 0.1 feet). See Table 2.
MW04-193- T NETrM System Automatic Free Product Recovery:
Free product recovery rate: 0.02 gallons/day (Note that this is the average rate of recovery from the NETrM system over the reporting period, initial recoveries were approximately I gallon/day) Total product recovered to date: 121.36 gallons (estimated)
MW-2 Manual Free Product Recovery:
A total of approximately 5 gallons of free product have been removed and disposed of from well MV¢-2 since recovery was initiated.
SYSTEM CHANGES
Describe in detail any changes in system operation or configuration made during this reporting period (attach additional pages if needed). Also explain any periods during which the system was not operating. 2 The NE’ITM System is designed to cycle on and offautomatically on a pre-set schedule to remove free
product at the most efficient rate and it currently operates Monday, Wednesday and Friday every week. The standard operating procedure is to cycle the system, so product is typically removed once per day, running for 35 minutes per cycle. During routine (at least quarterly) inspections, the run time for each cycle can be adjusted based on observations and judgment as to whether product is accumulating too quickly or too slowly to maintain efficient total recovery.
Guidance Document c-prp4-14: April 2005 Petroleum Remediation Program
Corrective Action Design SysteOnitoring Worksheet O Page 3
The NETrM system in well MW04-193-T is designed to be adjusted as needed to ensure efficient
product recovery. When recovery rates decline, the speed and/or duration of each extraction cycle can be decreased accordingly. Similarly, when product begins to accumulate more rapidly, the
speed and/or duration of each cycle can be increased.
The passive free product skimmer in well MW-2 was used until March 16, 2009 when it began collecting water in addition to product, indicating that the skimmer had removed a volume of product such that it was no longer an efficient method for recovery. As a result, absorbent socks are now being employed to recover the free product in the well.
RECOMMENDATIONS
List recommendations for modi~zing the monitoring schedule, system operation, system configuration or site closure (attach additional pages if needed):
Make adjustments to the NETTM system as deemed necessary in the field to improve the product
recovery rate. OBSERVATIONS
Please provide observations made at the site and describe unusual circumstance that may have influenced the sampling results:
The systems in both wells have been operating as expected. TABLES & GRAPHS
