1.0PURPOSE

The purpose of this procedure is to identify and control work place hazards. This procedure specifies the steps to be followed for permitting prior to performing any type of work. This procedure provides additional work permit requirements and information for work not covered in GSP-301, which is focused on “Hot Work” activities.

2.0SCOPE

This procedure covers all personnel; company or contractor, working in or on Valero Terminaling and Distribution Company (Valero) owned, operated or maintained pipelines, rights-of-way or facilities.

This procedure outlines the permit requirements, procedures, limitations and forms used in the issuance of Safe Work / Hot Work permits, including cold work, hot work, vehicle entry, excavation and confined space entry permits. This procedure assures the consistent Safe Work / Hot Work permitting within Valero facilities.

Safe Work/Hot Work (GSP- 301), Confined Space Entry (GSP-303) and Excavation (GSP-304) procedures have been developed to provide more detailed and specific information to provide a better understanding of the additional hazards and regulatory compliance associated with these higher risk activities.

3.0DEFINITIONS

Acceptable Entry Conditions The atmospheric, access/egress, and work area conditions that must exist, as defined in the Confined Space Entry Procedure, GSP-303, before entry is permissible.

Atmospheric Testing The process by which the atmospheric hazards which may confront personnel performing gas testing, hot work, or authorizing controls for confined space entry, are identified and evaluated.

Attendant or Designated Attendant For confined space entry purposes, an individual stationed outside the confined space (sometimes referred to as a “hole watch” or “fire watch”).

Authorized Entrant An employee or contractor who is authorized under the terms of the confined space entry permit to enter and exit the space only after signing in and out.

Blanket Safe Work / Hot Work Permit A permit issued to allow work on a grouping of closely interrelated or similar pieces of equipment. Blanket permitting is sometimes utilized during new construction or turnaround activity.

Cold Work Any work activity which does not supply sufficient heat or spark energy to provide a potential ignition source for a flammable mixture. This does not include, for the purposes of permitting, confined space entry, hot work, vehicle entry, or excavation. See specific General Procedures for these areas.

Competent Person In excavation work, a competent person is a qualified person capable of identifying existing and predictable hazards in the surroundings, or working conditions which are hazardous or dangerous to those performing the work, and who has the authorization to take prompt corrective action to eliminate them.

Confined Space Is a space which is:  Sufficiently large enough and so configured that an individual can bodily enter and perform assigned work

 Has limited or restricted means for entry/egress

 Is not designed for continuous occupancy The confined space may exhibit one or more of the following conditions  Contains or has the potential to contain a hazardous atmosphere

 Contains a material capable of engulfing an individual

 Has an internal configuration such that an entrant could be trapped or asphyxiated by inwardly converging walls or by floors which slope downward and taper to a smaller cross-section

 Contains any other recognized serious safety or health hazard

Examples of a confined space include, but are not limited to: 3.1. Tanks 3.2. Vessels 3.3. Drums 3.4. Sumps 3.5. External floating roofs on storage tanks when the roof is 4 feet or more below the top rim of the tank 3.6. The space above or below an internal floating roof on storage tanks 3.7.

10.0 CONFINED SPACE ENTRY PERMITTING PROCEDURES

11.0 See GSP-303 11.1. Determining a Permit Required Confined Space

The Originator determines if the space to be entered meets the criteria set by OSHA for a permit required confined space. If a confined space exists, this procedure applies if the space meets all of the following: a. Is large enough for a person to enter and work in the space b. Entry or exit into the space is restricted or limited (restricted includes ladders, manways, crawl spaces, etc.) c. Is not designed for continuous employee occupancy

. If the space meets all of the above, the Valero Responsible Person and the Person Conducting the Work determine the type of confined space and which sections in this procedure to follow.

There are three types of confined space which are defined below: d. Non-Permit Confined Space requires the use of permit section A to document decisions e. Confined Space Requiring Ventilation for control of unacceptable atmospheric hazards, requires use of permits f. Permit Required Confined Space requires the use of the entire permit plus an emergency action plan if using ventilation) NOTE: Valero requires the use of a permit to document decisions made regarding entry into all confined spaces that fall into the three respective categories. These categories reflect the OSHA Standard for Confined Space Entry. However, A permit is required for entry into all confined spaces even though the terminology may suggest otherwise.

11.2. Permit Required Confined Space Program WARNING: Do not start here without determining type of confined space and preparing the site. See GSP-303 for Determining Type of Confined Space and Pre-entry.

The Person Conducting the Work must first ensure all the applicable requirements in sections 5.1, 5.2, and 5.3 (if using ventilation) are completed.

To reclassify a Permit Required Confined Space to a Non-Permit Confined Space, the following must be considered:  Evaluate the space to determine what hazards are expected to be associated with entry. If there are no atmospheric hazards and if all non- atmospheric hazards within the space are eliminated without entry into the space, a Permit Required Confined Space may be reclassified as a Non-Permit Confined Space for as long as those hazards remain eliminated (see Confined Space Evaluation Form in Appendix D).

 If it is necessary to enter the Permit Required Confined Space to eliminate hazards, use this section ("Permit Required Confined Space") for entry requirements.

 If during entry, monitoring demonstrates that all the hazards within the space have been eliminated, the Permit Required Confined Space may be reclassified to a Non-Permit Confined Space for as long as the hazards remain eliminated. Work may then continue as outlined in section 5.2.

NOTE: A space cannot be reclassified to a Non-Permit Confined Space by using forced-air ventilation, because forced-air ventilation does not eliminate the hazards

In conjunction with planning the work, The Valero Responsible Person completes a written Emergency Action (see GSP-303 for Emergency Action Plan Form).

The Person Conducting the Work ensures that the following additional equipment is at the work site and is in good working order:  Ventilating equipment needed to obtain acceptable entry conditions must meet all the requirements in GSP-303

 Rescue and emergency equipment needed as specified in the Emergency Action Plan, except for equipment that is provided by rescue services

 Any other equipment necessary as specified by the Valero Responsible Person for safe entry into and rescue from Permit Required Confined Spaces

 “Confined Space Entry Permit Required” sign is posted

Note: When using pneumatic equipment in a confined space, an air supply system must be used which will provide properly filtered air (e.g. compressor)? Air systems with nitrogen backup must not be used.

If ventilation is needed, the Person Conducting the Work completes the appropriate section of the permit and begins ventilation as outlined in GSP-303.

The Valero Responsible Person reviews the permit conditions and gas test results, approves the appropriate permit sections (if ventilation is needed) and completes the permit. The approved permit must be posted at the entrance to the space before work may begin.

The Attendant must remain at the entrance to the space, monitor activities and evacuate and/or summon help in the event of an emergency. The Attendant must also:  Continuously maintain an accurate count of authorized entrants in the Permit Required Confined Space and ensure that the permit accurately identifies who is in the Permit Required Confined Space

 Communicate with entrants as necessary to monitor status and to alert entrants of the need to evacuate the space

 Monitor activities inside and outside the space to determine if it is safe for entrants to remain in the space and evacuate the Permit Required Confined Space immediately if the Attendant detects a prohibited condition

 Summon rescue and other emergency services as soon as it is determined that entrants may need assistance to escape from Permit Required Confined Space hazards

Note 1: When the emergency action plan allows Attendant entry for rescue, Attendants may enter a Permit Required Confined Space to attempt a rescue if they have been trained and equipped for rescue operations and if they have been relieved by another Attendant.

Note 2: More than one attendant may be necessary when the confined space is of such a size or configuration so as not to provide the attendant/entrant visual contact (examples are towers, compartments, etc).

The atmosphere within the space must be tested continuously if authorized on the permit by The Valero Responsible Person. Gas testing must be conducted as necessary to ensure there is no accumulation of hazardous vapors. Results must be recorded on the permit every two hours. NOTE: When the space has been vacated for more than 30 minutes, gas testing must be conducted again before re-entry.

If a hazardous atmosphere is detected while working in a space, ventilation equipment fails, or a worker becomes ill, all of the following must occur: a. Each worker must leave the space immediately. b. The Valero Responsible Person must terminate the entry and cancel the permit if a condition not allowed under the entry permit arises in or near the Permit Required Confined Space. c. The space must be re-evaluated to determine how the hazardous atmosphere developed. d. All equipment must be thoroughly inspected. e. Measures must be taken to protect workers from the hazardous atmosphere before the next entry takes place. f. The space must be retested as outlined in GSP-303

Once the job has been completed and after workers have exited the space, the Person Conducting the Work will conclude the entry by closing off a Permit Required Confined Space. The Valero Responsible Person will cancel the permit by removing it from the site.

The Valero Responsible Person must review all permit-required entry operations. The review must identify any problems and document that all entrants were protected from hazards during the entry. The Valero Responsible Person will correct task-level problems locally prior to authorizing additional entries. The Valero Responsible Person must notify the editor of the General Procedures Manual to revise procedural problems. Deficiencies which could result in injury must be corrected before the next entries are authorized.

A review of the problems should be conducted with HSE to assure that these conditions are communicated and, therefore, do not occur elsewhere. (Examples of circumstances requiring review include unauthorized entry, detection of any hazard not covered by the permit, injury or near miss, and employee complaint).

The permit must be filed as outlined in section GSP-303.

12.0 PERMIT DISTRIBUTION, POSTING, AND CANCELING REQUIREMENTS

Safe Work / Hot Work permit copies must be distributed as follows:

 One copy will be posted at the control area (control room, operator shelter, etc.,)

 One copy must be posted at the work site for Cold Work, Hot Work, and Excavation. Confined Space permits must be posted at the entrance to the confined space.

The Valero maintenance or contractor representative must return the Safe Work / Hot Work permit to the control area upon completion of the work, shift change or expiration of the Safe Work / Hot Work permit, and sign-off on the permit.

The Valero maintenance or contractor representative must indicate if the job is complete or incomplete in the specified area of the Safe Work / Hot Work permit. The job site must be left in a clean and safe condition. Upon returning the Safe Work / Hot Work permit, the Responsible Valero Representative will inspect the job site and indicate if the work area is clean and safe in the specified area of the Safe Work / Hot Work permit.

If the job site is found to be unclean and/or unsafe, the Safe Work / Hot Work permit will be suspended by the Responsible Valero Representative until the jobsite has been cleaned and/or made safe. When signing the appropriate section of the Safe Work / Hot Work Permit, the Responsible Valero Representative will be canceling the Safe Work / Hot Work permit.

NO JOB IS CONSIDERED TO BE COMPLETE UNTIL SIGNED OFF BY THE QUALIFIED TERMINAL/PIPELINE REPRESENTATIVE.

Responsible Valero Representatives must retain all completed and cancelled Safe Work / Hot Work permits for filing/retention.

13.0 TRAINING

13.1. Valero Employees  Only personnel who have been trained will use Atmospheric Testing and monitoring instrumentation.

 Only personnel who have been trained as a Responsible Valero Representative will issue Safe Work / Hot Work permits. Initial training will be coordinated through Training Department, with the assistance of the HSE Group.

13.2. Contractors During the site-specific safety orientation, contractors will be informed of permitting procedures. Process unit overviews will be issued to contractors with each Safe Work / Hot Work permit issued. Contractor representatives will participate in a Joint Job Site Visit and discuss with the Valero Responsible Valero Representative the exact nature of the extent of the work planned.

Coordination of the work with Valero Maintenance and Operations is required. The details of how this coordination will be conducted will be determined by the local site representatives. Contractors will assure that communications with everyone covered by the Safe Work / Hot Work permit will include the process overview, MSDS, Specific Work Hazards, and other information communicated by the Responsible Valero Representative.
