(CRE) has been hired by ExxonMobil to help process a Non-Residential Building Permit Application for the installation of steel storage units on the Colony Mine Bench Pad Site located North of Parachute, Colorado. The intention of this application is to identify and permit 10 pad sites where 8' by 20' shipping containers can be placed and stored. The shipping containers are not for work offices or living facilities, and will only contain research equipment for work being performed at the Colony Mine. Due to the size of the containers exceeding 120 sq ft, the permit application is being provided. History: The Colony Mine is situated 16 miles northwest of Parachute off of County Road 215. Two accesses to the mine exist, the North Drift and the South Drift, as shown on the Site Plan. The bench at the entrance to the Colony Mine is composed of 200-300 feet of compacted rock fill and was constructed in the l 980's and sits at approximately 7020' elevation. This bench provides the structural integrity necessary for appropriate anchoring of containers of this size. Project: The Site Plan schematic displays ten general locations for box anchor pads. The pads are approximately 12 ft. by 24 ft. Anchors installed at the comers will be used to secure the 8 ft. by 8 ft. by 20 ft . steel boxes. From the previously approved office facilities for ExxonMobil, it has been necessary to increase the magnitude of the anchor system from the original Mobil Mini recommendations due to the hardness of the bench. Below is a photo of a similar anchoring system proposed to be used with the installation of these storage facilities. Colorado River Engineering has inspected these anchors and determined they meet or exceed the minimum requirements for anchoring systems as required per Garfield County code section 7-812 (D) (2).

Mobil Mini does not construct the 8'x20' storage containers and cannot provide structural information for the boxes. The proposed storage boxes are shipping containers that Mobil Mini purchases from various manufacturers. Due to the lack of design information, Colorado River Engineering inspected a similar Mobil Mini 8'x20' shipping container for structural compliance to the Garfield County regulations, in particular the 50 lbs/sq ft snow load requirements. As a design reference point, CRE has depended upon the International Organization for Standardization (ISO) which provides recommendations for the design, construction, materials, testing and inspection of ISO standard shipping containers and ISBU modules, and is in accordance with the requirements for steel dry freight containers by all certified global manufacturers. Reviewing the ISO requirements, the steel storage container appears to meet the general ISO recommendations. The roof is 36" corrugated steel panels butt jointed together and welded that span 8'. Per the ISO the roof material shall be Corten A (Weather and corrosion resistant steel) or similar and the visual inspection appears that the containers meet this criteria. The calculations performed at Colorado River Engineering show that the design snow load of 50 lbs/sq ft is obtainable as a minimum, with minor or no deflection. 2 P.o.

Containers shall be inspected prior to shipping and after receiving by ExxonMobil for apparent structure fractures or limitations due to excessive loading. If fractures are identified, ExxonMobil will notify Colorado River Engineering to perform a structural inspection of the container. Attached to this letter is the completed new construction commercial Building Permit application and required structural and geotechnical plans. We look forward to working with you on this through the application process. If you have any questions, please do not hesitate to call me directly at 970-625-4933 x 118. 3 P .0.
