DEQ and the City of Bozeman/CVS Pharmacy, through their consultant Tasman, do not object to the grading around M-37 described in your September 30th email. We are concerned about future access. Please provide contact information so arrangements can be made to continue access to M-37. You mentioned that a different engineer is designing the industrial site where you suggest future access will be located. Do you know if it is the same owner for this site? Please provide a contact name for the owner of the site if possible. Please let me now if you have questions.

Recently, we have been working on designing the rail spur line that will cross Mandeville Creek and access the tract of land (Tract 2‐B of COS 2153A) that monitor well M‐37 is located on. The access is challenging for rail design due to the geometry of the creek and the location of the monitor well. 2 Please see our attached plans. Sheet C3.0 best shows the proximity of the monitor well to the proposed grading. And sheet C3.2 shows a cross section at this location. Our design shows an estimated 0.6‐ft of fill around the bottom of the well casing. This would leave about 2.5‐ft of well casing exposed above the proposed finished ground level. We would like to know if the proposed grading around the monitor well will be acceptable. I also included an exhibit showing the current access and future access to the monitor well. Please see attached. Things have changed a little bit on site recently. Earlier this year, the road easement for Red Wing Drive was abandoned within the Montana Rail Link right‐of‐way. The at‐grade railroad crossing has been abandoned and removed at Frontage Road and North 7th Ave. MRL has installed a gate at the edge of their right of way near North 7th Ave. Without a gate code from MRL the current access to the monitor well is down a temporary access road running east‐west between the NorthWestern Energy gate station and the cell tower, then directly north. In the future we anticipate the access to the monitor well will be off of Wheat Drive and likely through an industrial site with a loading and unloading area. This site is currently being designed by a different engineer. Please let us know if you have any questions about our proposed plans.

I discussed your email with Jim Sullivan of Tasman Geosciences, the remediation contractor for the City of Bozeman and CVS Pharmacy who are responsible for the cleanup of the Bozeman Solvent Site. As I mentioned in previous discussions with you, M-37 is part of the groundwater monitoring program for the Bozeman Solvent Site. Although PCE concentrations in the M-37 are showing a decreasing trend, groundwater monitoring in this area needs to continue until remedial actions are complete. At this time, I cannot give an exact timeline for the groundwater monitoring. One option available is to find an alternate location for M-37 that is close to its current location, but outside of the proposed rail embankment, loading and unloading area, and heavy equipment traffic area. This would involve abandoning M-37 before construction activities then reinstalling M-37 after 3 construction activities. A new well would have to be installed in similar conditions as the existing M- 37 for comparable data collection. Similar arrangements have been conducted in another area of the Bozeman Solvent Site. DEQ must approve the relocation of M-37. However, DEQ will not require the City of Bozeman/CVS Pharmacy to relocate this well to accommodate construction. If the City of Bozeman and CVS Pharmacy agree to relocating M-37, it is unlikely that they will pay for the abandonment and reinstallation if the relocation is not required by DEQ. Because the well abandonment and well replacement is considered a remedial action (see §75-10- 701(20), MCA for the definition of remedial action) if a party other than the City of Bozeman or CVS Pharmacy conducts the remedial action, DEQ would require a work plan for the well abandonment/replacement, and DEQ would have to provide written permission for the work to be conducted (§ 75-10-711(9), MCA and ARM 17.55.110 (http://www.deq.mt.gov/dir/legal/Title17.mcpx)). I can provide more information on this third party process at a separate time. I think it would be beneficial to have a call between you, the property owner/rail line owner, Tasman, and DEQ to discuss how to move forward with the protection and/or relocation of M-37. Please let me know a few days and times that work for you and I will coordinate with Tasman. I also think it may be beneficial to meet on site to discuss the location of proposed improvement plans (e.g., rail line) and/or alternate locations for M-37. Tasman, on behalf of the City of Bozeman and CVS Pharmacy, will also need to discuss access arrangements for the well. DEQ does not need to be part of that discussion if access arrangements can be agreed upon. I look forward to discussing this with you further. Please let me now if you have any questions.

There are future rail lines that would be a part of a private rail siding going directly next to the existing monitor well M‐37. You had noted that it will be critical to avoid damage to or removal of the well as part of any construction. With the current rail configuration, we are showing fill at the location of the monitor well and it is quite close to the rail line. Right now we are looking at options to adjust the rail lines to stay away from the monitor well completely. We did want to get your thoughts on the location of the well relative to the private rail lines and other improvements. Do we need to worry about providing legal access to the monitor well via an easement or other agreement? Red Wing Drive is in the process of being abandoned which will change access to the well site.  Are there options to extend or provide protection around the monitor well?  Separation from improvements/disturbance?  What is the timeline for the well staying in place? I would imagine it would not be removed any time soon? Please let us know your thoughts and if it would be easiest to just jump on a call.

With this proposed design the monitor well would be in about 5‐ft of fill coming off the 2:1 rail embankment for the industry tack. The monitor well would be about 12‐ft horizontally off the edge of the rail. If we need to completely avoid the monitor well we would need to shift the industry tracks to the south by about 10‐ft which would eliminate some usable length of loading and unloading area. This would also push the fill slope for the switch pad about 10‐ft closer to Mandeville Creek. Perhaps the rail embankment could act as protection for the monitor well as opposed to leaving it out by itself to get hit by heavy equipment. Is it acceptable for us to stack a couple 3‐ft tall, 48‐in diameter sections of manhole cylinders around the monitor well to protect it within the rail embankment? I have seen this done before with a survey monument in an area of fill. ‐Eric Eric Foss, EI Civil Engineer 5 Allied Engineering Services, Inc. 32 Discovery Drive, Bozeman, MT 59718 Tel: 406.582.0221 x222 | Fax: 406.582.5770 Cell: 509.998.2797|Email: efoss@alliedengineering.com Web: www.alliedengineering.com [alliedengineering.com] DUNS: 00‐769‐3724 CAGE: 1GHU7
