Section 11 Hot Work Permit Date: June 1999 Washington Aqueduct Division

Risk Management Program

Introduction

The purpose of this section is to describe a consistent control mechanism to prevent fires from welding, cutting, drilling, grinding, soldering, brazing, explosive actuated tool use, hot tar operations, hot plate use, and open burning activities. In order to comply with 40 CFR 68.85, a permit is issued for hot work operations conducted on or near a covered process. This permit documents that the fire prevention and protection requirements in OSHA regulations, 29 CFR 1910.252 (a), have been implemented prior to commencing the hot work operations.

Permit Procedure

A hot work permit request form, Form K-1 included in Appendix K, must be completed by Dalecarlia WTP personnel or outside contractors for any hot work to be performed on or near hazardous material/chemical process and facilities as follows:

• Work on tanks, containers, piping feed systems, or ancillary equipment containing chemicals or fuels.

• Work in chlorine facility rooms or on any part of the nondiluted chlorine system.

• Work within 25 feet of any flammable/combustible material with NFPA fire rating of 2 or greater.

• Wherever confined space entry testing indicates a hazardous atmosphere.

• Wherever a “Hot Work Permit Required” sign is posted.

• Work, where in the Foreman’s judgement that ignition/explosion of chemicals could occur from sparks, hot slag, etc.

The work site Foreman and the WA Safety and Occupational Health Program Manager or WA Project Engineer will review the proposed task and provide authorization that hot work is required. A hot work permit is then issued to the designated maintenance staff or contractor. This permit documents that appropriate fire prevention and protection requirements have been implemented prior to beginning hot work, the object(s) upon which hot work will be performed have been identified, and the dates for this work have been authorized.

The maintenance staff reviews all appropriate safety precautions to be taken prior to performing the hot work with the work site Foreman, including lockout/tagout, respiratory protection, use of personal protective equipment, etc.

When contractors perform work on WA property and lines, the maintenance staff will point out to the contractors where hot work permit procedures are required.

Section 11 Hot Work Permit

Dalecarlia Water Treatment Plant Risk Management Program / 11-2

Normally, hot work permits expire once each individual task is completed and at the end of the work day. A new permit is completed and issued at the beginning of each work day. However, extended contracts may be issued based on work/tasks to be performed.

After the designated maintenance mechanic or contractor completes items 1 through 6 of the Hot Work Permit Request form, the form must be submitted to the work site Foreman for review and signature of approval. The Foreman then passes the form to the WA Safety and Occupational Health Program Manager and/or WA Project Engineer for review and signature of approval. If the work is to be performed in a confined or poorly ventilated space, the Hot Work Permit Request form must be accompanied by a Confined Space Certificate (when applicable) issued and signed by a Confined Space Technician who has performed all tests and procedures required by the Confined Space Entry Program. The approved Hot Work Permit Request form becomes the hot work permit.

One copy of the hot work permit form is assigned to the maintenance staff or contractor who displays it at the work site until all hot work operations are finished. A second copy of the form remains in the hot work permit issuance book maintained by the WA Safety and Occupational Health Program Manager.

Upon completion, the maintenance staff performs any necessary unlocking/untagging, testing, or other activities necessary to return equipment to service and will notify the work site Foreman that operations may return to normal.

1.10 SEQUENCE OF CONSTRUCTION

1.10.1 General

Contractor shall construct work included under this contract in accordance with the following sequence of construction restrictions. Restrictions have been placed on when work can be completed within existing treatment facilities to ensure that adequate water production capacity remains in service to meet peak finished water demands and to ensure that the water treatment plant continues to comply with existing permit requirements. If specific calendar dates are listed below, they shall be considered unchangeable. The following construction sequencing requirements apply to this project:

a. Work associated with modifying the four existing sedimentation basins and related residuals collection and air release facilities shall be completed one basin at a time during a single winter low demand period from November 1st and March 31st. Work that impacts the ability to treat water through the four existing sedimentation basins will not be permitted to take place outside of the winter low demand outage period defined above. Work on the piping systems serving each individual sedimentation basin shall be completed during a single basin shutdown period lasting no longer than 15 days, exclusive of basin drain-down period. All four individual 15-day basin shutdowns shall be completed one basin at a time within the single winter low demand period defined above. Ideally, work on the existing electrical and control systems related to the installation of new residuals transfer pump variable speed drives, existing pump suction isolation valve controls, and air release valve actuators will also be completed within the same winter low demand period used to complete the basin piping modifications. If the electrical equipment is not available for installation within the first winter low demand period, the electrical and associated control modification can be completed outside of this low demand period provided it impacts no more than one basin at a time in accordance with the allowable power outage periods defined below. Control modifications shall be coordinated with the electrical work to ensure that control logic remains consistent with the number of variable speed drives available for service and the desired operating procedure for the residuals transfer pump suction isolation valves as the work progresses.

1. Sedimentation Basin No. 1: Work within this basin is related to core drilling holes through the wall that separates the center gallery between basins 1 and 2 to install new air vent goose neck piping. Coordinate with Washington Aqueduct staff to define the length of the required basin outage within the allowed 15-day

SECTION 01 05 00 Page 6 window and the basin drain-down level required to accomplish this work. Contractor shall maintain power to the basin drain-down pumps during the basin drain-down period.

2. Sedimentation Basin No. 2: Work within this basin is related to core drilling holes through the wall that separates the center gallery between basins 1 and 2 to install new air vent goose neck piping. Coordinate with Washington Aqueduct staff to define the length of the required basin outage within the allowed 15-day window and the basin drain-down level required to accomplish this work. Contractor shall maintain power to the basin drain-down pumps during the basin drain-down period.

3. Sedimentation Basin No. 3: Work within this basin is related to installing new air vent goose neck piping on each side of the basin at the upper level. Coordinate with Washington Aqueduct staff to define the length of the required basin outage within the allowed 15-day window and basin drain-down level required to accomplish this work. Contractor shall maintain power to the basin drain-down pumps during the basin drain-down period.

4. Sedimentation Basin No. 4: Work within this basin is related to installing new air vent goose neck piping on each side of the basin at the upper level. Coordinate with Washington Aqueduct staff to define the length of the required basin outage a within the allowed 15-day window and basin drain-down level required to accomplish this work. Contractor shall maintain power to the basin drain-down pumps during the basin drain-down period.

b. The Contractor shall provide at least 90 days advanced notice to Washington Aqueduct prior to performing any work in the sedimentation basins or disconnecting power or control circuits serving any existing water treatment equipment. Washington Aqueduct shall respond to the request within 10 days of receiving the request.

c. All draining of sedimentation basins shall be completed by Washington Aqueduct staff. Contractor shall allow 7 days for each basin to be drained, cleaned and flushed. The existing basin drain pumps shall remain operational during the period while the basin is drained.

d. Modifications to suction or discharge piping, controls serving the residuals transfer pump automatic suction isolation valves and new variable speed drives, and existing electrical equipment assigned to each set of three residuals transfer pumps dedicated to a given sedimentation basin shall be completed so as to minimize the impacts on the removal of residuals from that basin. Under no conditions shall the Contractor remove more than one residuals transfer pump from service at a time per basin if that basin remains in service. During this period, the two remaining residuals transfer pumps assigned to that basin shall remain in service.

e. Short duration power interruptions (up to 4 hours) will be permitted to install new breakers and VFDs in existing motor control centers serving in service basins.

1. A single 4- to 6-hour power interruption will be permitted to modify existing switchboard D-57 that serves all four sedimentation basins. Temporary power generation and cabling shall be provided by the Contractor to power the existing

SECTION 01 05 00 Page 7 sedimentation basin flocculators and the existing 480V-120/208V transformer located in the Substation Building during this period.

2. Several power interruptions of up to 4 hours each will be permitted to modify existing MCC-D57 to replace the existing starters with new VFDs.

3. A single 4-hour power interruption will be permitted to modify MCC-D61. This outage will only impact basins 3 and 4.

4. A single 4-hour 120V power and fiber optic relocation/reconnection period will be permitted to relocate control panels CP-22-3-1 and

CP-22-4-1.

5. The scheduling of all work of this type shall be approved by Washington Aqueduct at least 90 days ahead of time.

f. Power and control circuits for all sedimentation basin flocculators, residuals collectors, residuals transfer pumps, basin drain pumps, level control devices, basin utility outlets and basin lighting shall be maintained in service at all times unless a basin is removed from service to perform modifications, as described above, or an individual residuals transfer pump assigned to an in service basin has been approved for shutdown to perform modifications.

g. Installation of density meters at in-service basins shall be accomplished one basin at a time during a single 4 hour residuals flow outage.

h. Installation of air release piping and valves shall be accomplished one basin at a time during a single 30-day basin outage period. Residuals pump VFD and air vent piping modifications for each basin shall be accomplished during this same 30-day period.

i. Modifications to the existing SCADA control panels (CP-D57 and CP-D61) to install the new I/O cards for analog signals associated with the VFD speed control, pressure transmitters and density meters shall be accomplished one panel at a time during a single 8-hour control system outage per panel. The outage will impact the two sedimentation basins served by each panel.
