OOCD-0001, Rev. 38
1.0 INTRODUCTION
The Waste Isolation Pilot Plant (WIPP) was authorized by Congress (Department of Energy National Security and Military Applications of Nuclear Energy Act of 1980 [Public Law 96-164]) to provide "a research and development facility to demonstrate the safe disposal of radioactive wastes resulting from the defense activities and programs of the United States exempted from regulation by the Nuclear Regulatory Commission."
To fulfill this mission, the U.S. Department of Energy (DOE) constructed a full-scale facility to demonstrate both technical and operational principles for the permanent isolation of transuranic waste. The WIPP disposal facility horizon, which includes construction (mining) and experimental and waste disposal areas, is located approximately 2,150 feet below the surface in the Salado Formation, a thick sequence of evaporites that are predominantly halite.
The WIPP underground ventilation system consists of three intake vertical shafts, interconnecting drifts and cross-cuts. Bulkheads, airlocks, and salt pillars separate the drifts. The drifts are connected to an exhaust shaft that connects to the main surface fans.
2.0 PURPOSE STATEMENT
This plan satisfies the requirements for a mine ventilation plan as required by Title 30 Code of Federal Regulations (CFR) §57.8520, "Ventilation Plan," and the "New Mexico Safety Code for All Mines." It is based on current plans, conditions, and assumptions concerning the operation ofWIPP. This document will be revised at least annually to reflect any ventilation system changes.

5.0 ONE-YEAR PROJECTION MINE MAP
See Appendix B for a mine map showing significant changes in the ventilation system projected for one year.
6.0 MINE VENTILATION FANS
6.1 Mine Fans and Exhaust Filter Building (EFB) Fans
A total of six surface ventilation fans (e.g., three main fans and three filtration fans) supply airflow to the underground. The main fans are 700A, 7008, and 700C. The filtration fans are 860A, 8608, and 860C. The main fans and filtration fans are located on the surface of the WIPP facility atop the Exhaust Shaft (ES), and are operated in various configurations to provide the necessary airflow to the underground. Table 1, Fan Specifications, lists the physical and operating data of these fans. The fan curves are located in Appendix C.

ISSUED WIPP Mine Ventilation Plan
OOCD-0001, Rev. 38
Due to a radioactive particulate release in February, 2014, the main fans (700A, B, and C) have been locked out and will remain inoperable indefinitely. The WIPP underground is currently being operated in Filtration Mode. Filtration Mode consists of one 860 fan operating at a nominal 60,000 cubic feet per minute (cfm). The exhaust air from the underground is pulled by the fan through the exhaust shaft to duct on the surface. The air flows through the duct to two parallel HEPA filter assemblies located in the Exhaust Filter Building (EFB) on surface where the radioactive particles are removed from the air stream. The filtered air is then exhausted through the fan and the exhaust duct to atmosphere.

6.2 Face Ventilation Fans
WIPP Mine Ventilation Plan OOCD-0001 , Rev. 38
Diagrams showing the typical working face ventilation are found in Appendix D. One or two 100-HP Spendrup 1120-70 fans (in series as necessary) are used with ventilation ducting to exhaust the dead-end working faces. The fan curve and a fan pressure table are located in Appendix C. The face ventilation fans generally exhaust 50,000 cfm from the working area.
7.0 NUMBER AND TYPE OF INTERNAL COMBUSTION ENGINES USED UNDERGROUND
Table 2 lists the internal combustion engines used underground, along with the make and model of the unit, type of engine, make and model of the engine, brake horsepower rating of the engine, and the approval number.
Ventilation requirements for engines that do not have an MSHA Certificate number are calculated based on the VUOO System Design Description requirement of 125 cfm per brake-horsepower.

8.0 VENTILATION SYSTEM DESCRIPTION
The WIPP underground ventilation system consists of three vertical intake shafts, interconnecting drifts and cross-cuts. Bulkheads, airlocks, and salt pillars separate the drifts. They are connected to a common exhaust, which connects to the main surface fans. Figure 1, WIPP in Perspective, shows the relationship between the surface, shafts, and the underground repository. The airflow patterns and ventilation control devices are shown on Appendix A, Drawing No. 54-W-001-W (current revision). The four shafts are:
• Air Intake Shaft (AIS) • Salt handling Shaft (SHS) • Waste Shaft (WS) • Exhaust Shaft (ES)

Figure 1, WIPP in Perspective
8.1 Ventilation System Description and Configurations
The three intake shafts supply air to the repository level, consisting of four separate air splits, and it is discharged through a common exhaust shaft.
• The North Ventilation Circuit receives intake air from the Air Intake Shaft (AIS) and is used to ventilate the North Area, which includes materials storage, an experimental area, and the underground diesel maintenance shop.
• The Construction Ventilation Circuit receives intake air from both the AIS and the Salt Shaft (SS). The air travels south in W30 to the construction (mining) panel where it is used to ventilate the mining face.
• The Waste Handling Ventilation Circuit receives intake air that is split off the Construction Ventilation Circuit through a regulator at S1000/E20. The air travels south in E140 to the disposal panel.
8
ISSUED WIPP Mine Ventilation Plan
OOCD-0001, Rev. 38
• The Waste Shaft Station Ventilation Circuit receives intake air from the Waste Shaft. The air ventilates the waste shaft station area, then is exhausted to the east in S400, directly to the Exhaust Shaft (ES).
8.2 Filtration Mode Ventilation
The WIPP site experienced a radioactive particulate release in February 201"4. The ventilation system shifted to Filtration Mode at that time. The ventilation system has remained and will continue to remain in Filtration Mode for the foreseeable future.
Filtration Mode consists of the following:
• One 860 filtration fan operating in conjunction with a High Efficiency Particulate Air (HEPA) filtration system located in the Exhaust Filter Building. The main fans and bypass plenum to the 860 fans are isolated. Two HEPA filters at 100 percent capacity each work with one 860 fan to provide 60,000 cfm in this mode.
• The 74-8-336 bulkhead door (E300/S350) is closed. This closes off the exhaust path for the North Ventilation Circuit. Any air movement in the North Ventilation Circuit is via leakage through bulkheads.
• The 74-8-313 regulators (S1 OOO/E20) are closed. This prevents air from splitting off of the Construction Ventilation Circuit to ventilate the Waste Handling Ventilation Circuit. Any air movement in the Waste Handling Ventilation Circuit is via leakage through bulkheads from W30 to E140.
• The construction split regulator (74-8-707 at W170/S2000) is closed. This closes off the exhaust path for the Construction Ventilation Circuit. Any air movement in the Construction Circuit is via leakage through bulkheads to the Waste Handling Ventilation Circuit.
• The 74-8-308 regulator (S400/E280) remains open, allowing intake air from the Waste Handling Shaft to traverse across the waste shaft station and exhaust directly to the Exhaust Shaft.
Limited air flow in the underground limits the number of pieces of diesel equipment that may be operated at any one time. When diesel equipment is used for recovery work in the underground, regulators and bulkheads may be opened or closed as needed to move the limited air flow in the underground to specific work areas and/or ventilation circuits.

8.3 Additional Ventilation Control Features
8.3.1 Shaft Control Doors
The Salt Shaft, Waste Shaft and Air Intake Shaft are equipped with control doors. These doors may be closed as a means of controlling the spread of fire, smoke, or toxic gases.
8.3.2 Diesel Generator Operation
In the event of either a total or isolated power loss to WIPP which affects the filtration fans, WIPP is equipped with two backup diesel generators. One of these generators may be brought on-line within approximately 30 minutes of a power failure to restore filtration ventilation to the underground.

Dynamic Losses
The pre:s:mn•loss in each filling, inlet 11nd outlet must he co"Llculated separately and is b,ned on the velocity pr~jl.tiN of air at that point in the system.

Friction Losses
Friction loss curves, whkh arc prov1ded in this htcx:hure, are designt.-d to give the pre!;sure loss due to friction in thE- duct. The curves are based on the following fonnula:
