Maintenance procedures, Preventative Maintenance System (PMS), H-14 labeling, training or other support are not funded as part of the scope of the TWRS Safety Upgrades Project.

The installation design efforts were for three single tank installation ECN's. The scope of work to be performed by the TWRS Safety Upgrades Project does not include engineering tasks or hardware procurement for exhausting dual tanks with one exhauster.

The Scope of the TWRS Safety Upgrades Project includes only the preparation of applicable generic NOC radiological and toxic permits.

The TWRS Safety Upgrades Project assumed the utilization of experienced shop personnel for on site fabrication to reduce engineering follow requirements.

The 500 cfm portable exhauster design will be identical to the 241-A-101 exhauster, with minor Lessons Learned upgrades. The new off site design of the 1000 cfm portable exhauster will be similar to existing 500 cfm design in electronic and instrumentation and control configurations.

The off site procurement unit cost was assumed t o be 250K, with provisions for a CAM and GEMS system installed.

The off site fabrication activity will produce 2 units.

The Saltwell Stabilization program shall identify tank and riser locations by no later than 06-26-97 to avoid delaying design and fabrication schedules.

SUBJECT: P lan t Forces Work Review (PFWR) and Sal twel l Por tab le Exhausters

Gary,

Curren t ly we a r e in t h e planning s tages of a t a s k t o f a b r i c a t e and i n s t a l l t h r e e 500 cfm por tab le exhaus te rs . v e n t i l a t e s ing le-she l l t anks (SST's) during s a l t well pumping. The exhaus te rs may conceivably be i n s t a l l e d i n a s ignal loca t ion f o r a dura t ion of one t o t h r e e years .

The exhausters wi l l be employed t o

Each exhauster w i l l be equipped w i t h a programmable l o g i c c o n t r o l l e r (PLC). The func t ion of t h e cont ro l system i s t o enable proper operat ion of t h e exhauster and a l e r t personnel of alarm s i t u a t i o n s . The components mentioned above a r e mounted t o a support frame "sk id" constructed of carbon s t e e l channel. equipped w i t h f o u r l e v e l i n g jacks . The jacks wi l l be employed t o leve l t h e sk id on uneven t e r r a i n . A complete exhauster package measures approximately 2 2 ' long by 6 ' wide. L i f t i n g lugs a r e mounted t o each t h e sk id w h i c h provides t h e c a p a b i l i t y of moving exhausters form one loca t ion t o another through t h e use of a c rane and t r a n s p o r t t ruck .

equipment temporarily installed within a system is not to be interpreted as a facility modification.

Please provide your written thoughts concerning this issue.. I would like to add this information to my 500 cfm portable exhauster fabrication and installation engineering task plan, provided a PFWR i s indeed not warranted. It will provide traceability indicating that the PFWR was addressed for the task described therein. above for you to express your decision.

Hopefully, there is enough information furnished

Thanks Eric

Eric, thanks for the information.

The aforementioned regarding the fabrication and installation of a portable exhauster mounted on a skid to support salt well pumping, does not come under the constraints of the Davis-Bacon Act.

The Department of Energy Acquisition and Regulations (commonly known as the DEARS is used as the criteri; base for the DOE, Labor Standards Board to make decisions on PFWRs) states, applicable to the Davis-Bacon Act. support operational type activities that doesn't have any construction activities associated with it, and is not a logical part of a construction project. Forces.

This portable piece of equipment could have been procured, fabricated offsite, delivered to Hanford, placed in the farms, and plugged into an existing power source. Instead Tank Farms decided to fabricate the equipment on-site instead of procuring it off-site, and this i s their prerogative.

However, if this work at any time requires excavation, new conduit runs or concrete poured to support the skid then a PFWR would be required.

If you have any questions feel free to call me on 376-1676.

Thanks again Eric for the complete information.
