SCOPE OF WORK

The Gas Management System Rehabilitation and Improvements Project -

Regional San operates a digester gas management system (GMS) for treatment, delivery, and disposal of

the sludge gas produced by the anaerobic digesters. Low-pressure sludge gas is collected from the digesters

and typically treated for hydrogen sulfide using a series of iron sponge media scrubbers. The scrubbed gas

is then compressed (medium-pressure sludge gas) and, under normal operation, transferred to the Carson

Cogeneration Facility (Cogen) and the Regional San boilers. When there is excess sludge gas produced or

if Cogen is not available, the low-pressure sludge gas can be disposed at the enclosed flares or the Waste

Gas Burners (WGBs). The WGBs can be used for disposal of scrubbed or unscrubbed sludge gas, while the

enclosed flares are limited to burning only scrubbed gas based on current permit requirements. Changes in

digester gas production and consumption has resulted in periodic uncontrolled venting from the digesters.

The GMS Improvements and Rehabilitation Project was initiated to prevent periodic uncontrolled venting

of digester gas and to bring the GMS into compliance. Because the GMS needs to remain in operation, the

Project will be staged into different phases of construction that will have critical durations. The scope of the

work includes improvements to the following areas within the GMS:

1. In and around the MSG Building

2. Ground Flares & WGB’s

3. LSG Scrubbers

4. LSG, MSG, & FSG Condensate Systems

5. LSG Holders & Horton Spheres piping

The work to be completed in RFB No. 8295 includes all labor, abatement and disposal cost, equipment and

materials necessary to complete this project as stated in this RFB and on the drawings and specifications.

The following documents are also incorporated into this contract:

Drawings: Gas Management System Rehabilitation and Improvements Project (full set)

Project Specifications

Sacramento County Standard Construction Specifications (current version) –

Such other items or details not mentioned above that are required by the plans or these specifications shall

complete the AR form. The requirement for a pre-AR meeting may be

waived by the District if the nature of the work is deemed to be minor.

The CONTRACTOR shall complete the AR Form (attached), and

submit in accordance with the SUBMITTAL PROCEDURES Section

(01 33 00) for approval by the District following the pre-AR meeting.

The District will distribute the AR for review.

a. The CONTRACTOR shall describe the nature of the work within the

AR form. The description shall include details of all relevant trades

associated with the required shutdown, diversion, or tie-in. If any of

the trades are subcontracted, the CONTRACTOR shall be responsible

for making the subcontractor provide and include the specific details

required by that trade for the associated shutdown, diversion, or tie-in.

b. The CONTRACTOR shall provide sufficient details on process

isolation, work sequencing, and safety (i.e., control of significant

hazards unique to the shutdown, diversion, or tie-in) to demonstrate

an understanding of the Work and how it will be completed within the

associated constraints, and the Work’s impact on the treatment

process. The District can provide information on the process-related

aspects of the shutdown during the pre-AR meeting.

c. CONTRACTOR shall include any work required by the District in

preparation of the CONTRACTOR’s Work and requested timing of

this work.

d. The AR will be reviewed for completeness, accuracy, compliance

tie-in does not negatively affect the operations or other concurrent

activities at the PLANT. Additional information may be requested

from the CONTRACTOR to understand the nature of the Work and

method for completing the Work activities. The District will return

the AR to the CONTRACTOR for revision if any of these criteria are

not met. Requirements for resubmittal or modifications resulting

from the District’s review shall not be cause for any delay claims.

Once the AR is acceptable to all parties, the AR will be accepted by

shutdown, diversion, or tie-in unless a longer period of time is

specifically called out in the specifications for a particular activity.

For each resubmittal resulting from the District’s review,

CONTRACTOR shall modify and update the associated AR within

seven (7) calendar days and allow an additional ten (10) calendar days

for District review and comments. Any resubmittal efforts associated
