SUBJECT: Task 3C - Industrial and Mining Water Use

The purpose of this technical memorandum is to document industrial water use in the Wind-Bighorn Basin (Basin) to support the Wind-Bighorn Basin Plan Update. This information updates and expands on work completed during the previous Wind-Bighorn Basin Plan completed in 2003 (BRS 2003). Section 1 provides a brief summary of industrial water use reported in the previous Basin Plan. The remaining sections provide updated information.

This technical memorandum contains the following sections.

Section 1 – Introduction

Industrial water uses such as those associated with mining, oil and gas, coal bed natural gas, and manufacturing companies, and their importance to the economy within the Basin, were described in the previous Basin Plan. Total industrial and mining water use in the Basin was estimated at 92,240 acre- feet per year based on well yield data from 1999. The majority of this water use was for oil and gas exploration and development, and was about 73,790 acre-feet per year. Manufacturing companies associated with mineral exploration, agriculture, and outdoor recreation used about 15,710 acre-feet per year. The remaining 2,740 acre-feet per year was used for mining related purposes (primarily mining for bentonite and gypsum), including about 500,000 gallons per month at a bentonite plant in Worland. Water supply for mining facilities was typically derived from groundwater aquifers, and water reuse for non-potable purposes such as dust control was common practice. This memorandum updates estimates of industrial water uses within the Basin.

Hydroelectric power production occurred within the Basin at six Bureau of Reclamation facilities, with total production capacity of 47,100 kilowatt hours. Water use for hydroelectric power production is a non-consumptive use, and demands for power production were not quantified in this memorandum. However, hydropower does create a “pseudo” consumptive use in that water is released during winter

months to generate power. This water is thus lost to other permitted uses such as irrigation as the requirements of the one-fill rule apply to reservoir storage.

There were no fossil fuel power plants (i.e., coal or natural gas electric power production facilities) in the Basin when the previous Basin Plan was completed. Water use associated with developing fossil fuel power plants from reserves in the Basin was estimated based on an assumed 200 MW coal-fired steam turbine facility and a 500 MW gas-fired combination turbine facility, and ranged from 4,000 acre feet per year to 5,000 acre-feet per year. Section 2 – Industrial Water Use

Industrial water uses in the Basin are water demands associated with industrial facilities, mining operations, coal bed natural gas and oil and gas production fields. A majority of the industrial water use in the Basin is from mining and oil operations and is difficult to quantify. Water used for mining and oil and gas production tends to be an impediment to or a by-product of the extraction process, with little attention paid to quantities withdrawn. As a result, industrial water use is often over-estimated based on maximum groundwater well yields or surface water rights.

In an effort to better quantify water withdrawals and consumptive use for the Basin Plan update, information on estimated water use was obtained from the U.S. Geological Survey (USGS) National Water Use Information Program (NWUIP). The NWUIP is responsible for compiling and disseminating the nation's water-use data. The USGS works in cooperation with local, state, and federal environmental agencies to collect water-use information aggregated at the county, state, and national levels. Every five years, data including information on water withdrawals for the categories of public supply and self-supplied domestic, industrial, mining, irrigation, and thermoelectric power are compiled into a national water-use data system and published in a national report. Based on information provided in these reports, more precise estimates for groundwater and surface water withdrawals and consumptive use for industrial operations in the Basin can be calculated.

The information below provides a summary of groundwater and surface water rights for Industrial use in the Basin obtained from the State of Wyoming, State Engineer’s, as well as estimates for groundwater and surface water withdrawals and consumptive use for industrial purposes based on data obtained from USGS NWUIP reports (USGS 2005, USGS 1995, USGS 1990). Section 3 – Industrial Groundwater Use

Industrial groundwater uses in the Basin are water withdrawals from permitted wells associated with self-supplied industrial facilities and operations. Currently, there are 347 groundwater wells permitted to supply industrial operations in the Basin. Of these wells, 216 have a yield of at least 50 gpm. There are an additional 28 groundwater wells permitted for coal bed natural gas production 1. Well yields range up to 5000 gpm and 60 gpm for coal bed natural gas wells (WSEO 2010). Permitted production rates or well yields correspond to the maximum sustainable rate at which each well can be pumped and are not indicative of actual withdrawal rates for Industrial water use in the Basin. The locations for the industrial wells and coal bed natural gas wells are shown in Figure 1 and Figure 2. A complete list of permitted wells for industrial water use in the Basin is provided in Appendix A.

1 Note that the WSEO sent a query of all wells in Division III. This database contained 53 CBNG wells. However, when plotted in GIS, 25 of the wells plotted outside of the Wind-Bighorn Basin boundaries. Only those wells within the boundaries of the Wind-Bighorn Basin are plotted.

Industrial water use for the Basin was based on data published in the 2005 NWUIP report for mining and was calculated using a combination of national estimates, plus oil and gas data specific to Wyoming (USGS 2005). The national estimates include withdrawals for non-fuel mineral and coal mining and are based on coefficients, crude ore production data for 2004 from the USGS GD Minerals Information Team, and coal production from the Department of Energy (DOE) Energy Information Administration (USGS 2005). The coefficients were derived from various sources, including Bureau of Census and Bureau of Mines reports and withdrawal data collected by the USGS in individual states (USGS 2005). For some commodities where coefficients varied greatly, median or average values were used.

The industrial water use category in the NWUIP reports includes water that is withdrawn and used for industrial purposes such as fabrication, processing, washing, and cooling. The mining water-use category includes water that is withdrawn and used for non-fuels and fuels mining. Non-fuels mining includes the extraction of ores, stone, sand, and gravel. Fuels mining includes the extraction of coal, petroleum, and natural gas. Water is used for mining in the extraction of minerals that may be in the form of such solids as iron, sand, gravel, and coal; such liquids as crude petroleum; and gases such as natural gas. Water also is used for quarrying, milling (crushing, screening, washing, and flotation of mined materials), and other activities directly associated with mining. Only water for self-supplied industrial and mining users was included in the estimates and saline water use for mining activities is significant. Water use by industrial facilities associated with municipal water supplies was included in Tech Memo 3B, Municipal and Domestic Water Use.

For petroleum and natural gas mining, extracted water is often re-injected for secondary oil or gas recovery and/or discharged to surface water. Therefore estimates for oil and gas withdrawals in the NWUIP report were based on the volume of water injected and discharged at each well field. Records of produced water injected at oil and gas fields by county were obtained from the Wyoming Oil and Gas Conservation Commission. All water injected was assumed to be saline produced groundwater from oil or gas wells (no surface water). Records of permitted produced water discharges by county were obtained from the Wyoming Department of Environmental Quality (WDEQ) National Pollutant Discharge Elimination System (WYPDES) database. The data were summed by county and the resulting totals were added to estimated withdrawals for non-fuel mineral mining and coal mining (USGS 2005).

Estimated total industrial and mining groundwater use for the Basin is 91,258 acre-feet per year, with 806 acre-feet per year supplied from fresh water wells and 90,451 acre-feet per year supplied from saline groundwater wells (USGS 2005). Industrial withdrawals account for an estimated 224 acre-feet per year of fresh groundwater use (Table 1). Estimated groundwater use from mining is 91,034 acre- feet per year and includes 90,451 acre-feet per year of saline water (Table 1).

Consumptive groundwater use for industrial purposes was not reported in the NWUIP report for 2000 or 2005. Therefore, current industrial consumptive groundwater use for the Basin can be estimated by using historical consumptive use averages from the 1990 and 1995 NWUIP reports or by calculating consumptive use from estimated industrial groundwater withdrawals and permitted produced water return flow volumes.

Consumptive use estimates from the NWUIP reports are based on coefficients and range from 10 to 90 percent of withdrawals, depending on the type of industry or mining activity (USGS 1995, USGS 1990). Although coal bed natural gas production has increased in Wyoming since 1995, relatively few operations occur in the Basin and the overall use is small in comparison to oil and gas operations. Therefore, the coefficients used in 1990 and 1995 to estimate percent consumptive use should be comparable to current industrial and mining activity in the Basin. Percent consumptive groundwater use from the 1990 and 1995 NWUIP reports and the calculated averages for industrial and mining activities in the Basin are summarized by county in Table 2.

Table 2. Percent Industrial Consumptive Groundwater Use for the Wind-Bighorn Basin Industrial Mining Mining Fresh Water Consumptive Use Fresh Water Consumptive Use Saline Water Consumptive Use County (1) (1) (1) (% of Total Use) (% of Total Use) (% of Total Use) 1990 1995 Average 1990 1995 Average 1990 1995 Average Big Horn 15 14 15 25 41 33 0 40 20 Fremont 16 17 16 24 41 32 0 42 21 Hot Springs 17 25 21 24 41 33 0 41 21 Park 28 13 20 20 41 30 0 41 21 Washakie 16 13 15 22 42 32 0 41 21 Notes (1) NWUIP 1990-1995 consumptive use percentages were used for the calculations.

Based on calculated averages from the NWUIP reports, the estimated total consumptive groundwater use for industrial purposes for the Basin is 19,030 acre-feet per year, or 20% of total fresh and saline withdrawals. Consumptive groundwater use from freshwater withdrawals for self-supplied industrial facilities was 0.04 mgd, or 39 acre-feet per year. Consumptive groundwater use for industrial mining activities is 0.17 mgd, or 191 acre-feet per year for freshwater withdrawals and 16.8 mgd, or 18,880 acre-feet per year for saline withdrawals.

Based on industrial water use information provided by the NWUIP reports and WDEQ National Pollutant Discharge Elimination System (WYPDES) permits for produced water discharges in the Basin, the remaining portion of non-consumptively used water is either injected for oil and gas extraction or discharged to surface water (USGS 2005, WDEQ 2009). Produced water discharge is a bi-product of oil and gas production and is comprised of a portion of the water from the formation reservoir, additional water injected into the formation for gas extraction, plus any chemicals added during the production and treatment processes. As indicated above, water withdrawals for mining operations in the Basin was estimated by summing the total amount of water injected or discharged produced water from extraction processes (USGS 2005). Therefore, if it is assumed 100 percent of the non-consumptive use is discharged as produced water, e.g. no injection, consumptive groundwater use for the Basin can also be estimated by using the permitted return flow volumes for produced water discharges and estimated total industrial groundwater withdrawals from the 2005 NWUIP report.

Based on WYPDES permits for the Basin, total produced water discharge from industrial operations is 71,183 acre-feet per year (Table 3, Figure 3). As indicated above, total estimated groundwater use reported in the 2005 NWUIP for industrial and mining activities is 91,257 acre-feet per year. Assuming 100 percent of the non-consumptive use is discharged as produced water, the estimated total consumptive use for these operations would be 20,074 acre-feet per year.

Based on historical averages and permitted produced water discharges, the range of total industrial consumptive groundwater use for the Basin is 19,030 to 20,074 acre-feet per year, or 20 to 22 percent of total groundwater withdrawal. For reference, a complete summary of the current WYPDES surface water discharge permits for the Basin is provided in Appendix B.

Section 4 – Industrial Surface Water Use

Industrial surface water uses in the Basin are water demands and withdrawals from surface water rights associated with industrial facilities and operations. Currently, there are 68 surface water rights in the Basin permitted to supply industrial water use that are not directly associated with municipalities. Twenty-five are rights associated with reservoir storage and 43 are rights associated with permitted stream flows (WSEO 2009). Total capacity for the 25 permitted reservoir surface water rights is 6,128 acre-feet per year. Total capacity for the 43 permitted stream flow surface water rights is 1,134 cfs (WSEO 2009). Capacities for reservoir storage and permitted stream flow were estimated using only permitted industrial water rights not associated with municipal water supplies. Additional industrial water uses supplied by municipal water supplies (e.g. Buffalo Bill Reservoir, Shoshone Pipeline) were accounted for in Tech Memo 3B, Municipal and Domestic Water Use. A complete summary of the surface water rights for industrial users, including permitted industrial surface water rights independent of municipalities as well as permitted industrial water rights associated with the municipal water supplies in the Basin is provided in Appendix A.

Estimated industrial surface water use for the Basin is 649 acre-feet per year (Table 4) and was calculated based on the same methodology described above in Section 3, Industrial Groundwater Use (USGS 2005). No saline surface water supplies exist in the Basin, therefore 100 percent of surface water use was supplied from fresh water sources. Total surface water use for industrial facilities accounted for an estimated 448 acre-feet per year and 201 acre-feet per year for mining operations. Similar to groundwater well yield, the portion of surface water use for industrial and mining activities in the Basin is small in comparison to the permitted capacity of the water right. The permitted capacities for surface water rights represent the maximum potential water supply of a water right and are not indicative of total water withdrawn. Availability of the source water for each right is dependent on the seasonally available supplies (low flow and peak flow) from the source water, as well as the priority date of the water right.

Consumptive surface water use was not reported in the NWUIP report for 2000 or 2005. Therefore, current consumptive surface water use for industrial purposes for the Basin was estimated using consumptive use averages from the 1990 and 1995 NWUIP reports. Consumptive use estimates for industrial surface water use are based on the same coefficients for groundwater use summarized in Section 3 and range from 10 to 90 percent of withdrawals depending on the type of industry or mining activity (Table 2).

Based on calculated averages from the NWUIP reports, the estimated total consumptive industrial surface water use for the Basin is 133 acre-feet per year, or 20% of the total fresh water withdrawals. Estimated consumptive surface water use is 67 acre-feet per year for industrial facilities and 66 acre-feet per year for mining activities in the Basin. Industrial consumptive use estimates for the Basin were based solely on water rights from fresh water stream flows. Consumptive use from surface water stored in reservoirs was accounted for in Tech Memo 3F, Water Use from Storage.

Section 5 – Summary

Estimated industrial groundwater use for the Basin is 91,257 acre-feet per year, with 806 acre- feet per year supplied from fresh water wells and 90,451 acre-feet per year supplied from saline groundwater wells (USGS 2005). Self-supplied industrial withdrawals account for an estimated 224 acre-feet per year of fresh groundwater use (Table 1) and include water used for industrial purposes such as fabrication, processing, washing, and cooling. Total estimated groundwater use for mining is 91,033 acre-feet per year and includes 90,451 acre-feet per year of saline water (Table 1). Based on calculated averages from the NWUIP reports and WYPDES discharges in the Basin, the estimated total consumptive groundwater use for industrial purposes for the Basin ranges from 19,030 to 20,074 acre-feet per year, or 20 to 22 percent of total industrial groundwater withdrawals.

Estimated industrial surface water use for the Basin is 649 acre-feet per year, with 100% supplied from fresh water sources (Table 4) (USGS 2005). Industrial withdrawals account for 448 acre-feet per year of surface water use and 201 acre-feet per year for mining. Based on calculated averages from the NWUIP reports, the estimated total consumptive industrial surface water use for the Basin is 133 acre-feet per year, or 20% of the total fresh water withdrawals. Consumptive surface water use for industrial facilities is 67 acre-feet per year and 66 acre-feet per year for mining activities in the Basin. No surface water withdrawals or consumptive use for industrial purposes for the Basin occurred from saline water sources. A summary of total industrial water use and consumptive use from groundwater and surface water supplies in the Basin is provided in Table 5.

Estimated industrial water withdrawals for the updated Basin Plan Report are similar to those reported in the previous Basin Plan. Industrial water use in previous Basin Plan was slightly higher, with total withdrawals estimated at 92,240 acre-feet per year, based entirely on permitted water rights from the WSEO office in 1999. Estimated consumptive use for the updated Basin Plan Report is significantly lower than those reported in the previous Basin Plan. Consumptive use estimates were not calculated in the previous Basin Plan and were assumed to be 100 percent of permitted water right. Estimates in the updated Basin plan report for

consumptive use are 20 to 22 percent of the total withdrawal and are based on historical and industry specific data for the Basin.
