Northern Natural Gas Request for an Essential Services Permit 4ROSEMOUNT EXECUTIVE SUMMARY PLANNING COMMISSION Planning Commission Meeting Date: November 26, 2013 Tentative City Council Meeting Date: December 17, 2013 AGENDA ITEM: Case 13-34-ESP Northern Natural Gas AGENDA SECTION: Request for an Essential Services Permit for Public Hearing a Natural Gas Line to Serve Flint Hills PREPARED BY: Eric Zweber, Senior Planner AGENDA NO. 5.e. ATTACHMENTS: Pipeline Project Maps; Project Description APPROVED 12V Narrative RECOMMENDED ACTION: Motion to recommend that the City Council approve the Essential Services Permit for Northern Natural Gas, subject to the following conditions: 1. Submittal and approval of a City Utility Permit from the City Engineer. 2. All construction and restoration activities shall conform to the City of Rosemount General Specifications and Standard Detail Plates for Street and Utility Construction. ISSUE Northern Natural Gas Company (NNG) is proposing to install a 12 inch natural gas pipeline to provide service to the Flint Hills Resources refinery. The pipeline will connect the existing 30 inch pipeline located about a '/z mile south of County Road 46 in Coates to the refinery. Under the zoning ordinance, this type of transmission utility activity requires an essential services permit. SUMMARY NNG currently provides natural gas to the Flint Hills Resources refinery through a pipeline running parallel to US Highway 52 about '/a mile east of the roadway. The pipeline connects an existing pipeline running about 1/2 mile south of County Road 42 to the refinery. In 2012, service from this line was disrupted and stopped natural gas delivery to the refinery and forced some refinery production to shut down. To provide redundancy which would limit the potential for natural gas disruptions to the refinery, NNG is proposing to install a second 12 inch pipeline to the refinery. To provide the most redundancy, the new pipeline will start at a different 30 inch trunk pipeline than the existing service line and will follow a separate easement to limit any disruption that could occur during construction or repairs of the existing pipelines. The new pipeline will begin in the City of Coates about 1/2 mile south of County Road 46, run along the western boundary of Coates crossing County Road 46 and then running along the northern boundary of Coates to US Highway 52. From this point,it will run parallel to US Highway 52 on the east side of the highway about 1,000 feet, then cross US Highway 52, and then run parallel to the roadway, on the west side, to the point where the City has adopted an official map for the new US Highway 52 and County Road 42 interchange. At this location, NNG proposes to run the pipeline directly west about 400 feet and then directly north about 1,500 feet including a crossing of County Road 42. The final segment will run roughly northwest along the former railroad line until it is west of the CHS trucking facility and finally run directly north into the refinery including a crossing of 140th Street. Pipeline Construction Methods and Roadway Crossings NNG will be constructing the pipeline by digging a trench along most of the route with exception of the road crossings. NNG will directional bore the pipeline at the four road crossings (County Road 46, US Highway 52, County Road 42 and 140`h Street) and the rail line on the south side of the refinery. The City has jurisdiction over only one of those streets, 140`h Street, and staff has a recommended condition that NNG will need to apply for and receive a City Utility Permit that will regulate the crossing of 140`h Street. The other three street crossings will need either State or County approval. NNG has been discussing the crossings at County Road 42 and County Road 46 with staff at Dakota County. There is particular concern about any crossing of County Road 42 because of the plans to reconstruct the interchange into a cloverleaf. Dakota County staff is supportive of the pipeline crossing in the location proposed because it is in close proximity to the MinnCan oil pipeline and the Metropolitan Council sanitary sewer line. Dakota County staff prefers to have all major utility crossings in the same general area instead of being widely distributed along the road right of way. NNG proposes three staging areas for the project where pipes will be delivered and the construction equipment will be maintained. Those three locations are at the crossing of County Road 46,about a half a mile north of County Road 46, and at the crossing of 140th Street. The City has regulations regarding hours of operations, dust and erosion control, noise and maintenance of construction activity. Staff has recommended a condition of approval that clarifies that that NNG and their contractors will need to meet these regulations. Southeast Corner of CSAH 42 and US Hwy 52(Rechtzigel properties) Leslie Rechtzigel has contacted staff to express concern regarding the negotiations with NNG for the pipeline alignment. Ms. Rechtzigel has stated that she prefers that NNG follow the existing pipeline along their southern property line and then follow the MinnCan pipeline along the east side of the former railroad tracks. City staff has no opinion on which alignment the pipeline should take through the Rechtzigel property as long as it crosses County Road 42 near the former railroad tracks. NNG needs to acquire the easements for the pipeline from the property owners along the route. NNG has stated that they have a blanket easement across the Rechtzigel property from the 1940s, when the existing pipeline along the southern property line was installed. NNG staff is discussing the easement acquisition with Rechtzigels and they have stated that NNG wants to pay a fair market price for the easement. NNG has provided an alternative alignment on the plan sheet that would stay on the east side of US Highway to the CSAH 42/US Highway 52 interchange to avoid the Rechtzigel property, then bore the pipeline under the interchange at an angle to the northwest and connect to the alignment to Flint Hills. City staff is concerned that this alternative could have design and construction impacts on the future reconstruction of the interchange. It is ultimately the State or the County that would permit the crossing of the interchange. Staff has discussed the potential alignments with the County. The County staff stated that they are not supportive of the diagonal alignment. However, through the permit approval process NNG would need to relocate the line in the future at NNG cost if the pipeline would interfere with construction of the new interchange. RECOMMENDATION Staff recommends that the Planning Commission recommend approval of the Essential Services Permit subject to conditions provided. 2 i a II7 f , e `.:4.1.% q1 P I -''''.-,--,..-.'''s ri -e W w zo o ' 0 0o N a 1 1 � .r � �� �tI ? is'.o ''.r..7,:..-!-- � L .4a4';.d u � F m i Q '- cai h il -T-i'.. -r. _s . 7 {'1 •,f \4`i'- . w �°, w <icwixo s�; '. yC7. o o .0<iao , 2eo o y w y a E ytr: �R.• r_A ,, I T ..

Let me know if you have any questions. The purpose of this project is for Northern Natural Gas Company"Northern" to install a new 12-inch- diameter natural gas pipeline to provide increased operational reliability to the Flint Hills Resources Pine Bend Refinery. The 12-inch-diameter pipeline will be served from Northern's existing mainlines. The pipeline will terminate at a new delivery station located within Flint Hills Resources' property. A 100-by- 100-foot property will be required at the beginning of the pipeline to encompass the takeoff facilities. The project will require the acquisition of a new 50-foot-wide pipeline easements, and 50 feet of temporary work space will be required along the entire route. Additional temporary work space will be required for road and railroad crossings and points of inflection. Further, temporary work space will be required for equipment and material staging. Northern representatives will coordinate permitting activities with all jurisdictional authorities, including but not limited to Dakota County, City of Coates, City of Rosemount, Minnesota Department of Transportation, and Union Pacific Railroad. Northern will also coordinate permitting activities with all applicable environmental agencies. Construction is currently scheduled to begin in May 2014 and last approximately four months.
