The existingplant draws water from three upper Floridian Aquifer wells. The facility currently utilizes tw5 mgd membrane treatment nanofiltration skids and incorporates a raw water blend rate of approximately 15 percent (0 . 53 mgd) to achieve the facility finished water capacity of 3 .53 mgr d . The facility layout was designed for future expansion at such time customer demande in thh North County service area warranted . The original scope of services under Work Author No . 1 was to add only three new 1 .5 mgd nanofiltration skids during Phase II Expansion. Theon total plant rated capacity after this expansion would have been 7.5 mgd of permeate capacity , Based on IRC' s request to provide additional standby capacity, this will be modified unde Amendment No . 1 to include a total of six new 1 . 5 mgd nanofiltration skids . Based on the amended scope of services, the treatment plant will be designed to have permeate capacity of 12 mgd and a finished water capacity of 14 . 12 mgd (assuming 15 percent blend rate) . SCOPE OF SERVICES CDM shall provide the additional engineering services related to increasing the permeate wate production at the NCWTP to build-out with a capacity of 12 mgd of permeate flow. The r additional engineering services shall include updating the preliminary design report, completion of the final design to increase the permeate capacity to 12 mgd, permit modifications based on the amended scope of services, and construction services for the expansion of the IRC NCWTP to build-out. The intent of this authorization is for CDM to provide to IRC a set of Contract Documents suitable for public procurement for construction of the herein described facilities . The following described engineering services are additional scope items not previouslycovered in the Phase II plant expansion. These services will be addressed in the final plant desiand covered under this amendment: gn 1 The final design of all Phase II improvements by CDM will utilize the design intent and criteria provided in the NCWTP Expansion Preliminary Design Report prepared by CDM and dated December 2004 in conjunction with those modifications described herein, as requested by IRC. Subsequent to the review/ revision of the Preliminary Design Report, as described in Task 1 - "Review of Preliminary Design Report, " any B-1 mh2080. doc changes in design intent and criteria will be adopted and incorporated into the final design. Significant changes in the design intent and criteria which are not identified herein and that result in significantly altered or new facilities and/ or major equipment ui ment will be considered Additional Services not covered under this authorization . 2. Bench scale and pilot plant scale testing to determine membrane performance will no t b performed as part of this amendment. CDM will utilize full scale operating plant data ine conjunction with reasonably conservative design criteria in the final design of the Phase II build-out improvements . 3 . The existing facilities must remain in service during construction of the herein described Phase II improvements. Construction will be phased to incorporate the two new 1 .5 mgd nanofiltration skids in the existing process bay first followed by the four new skids in the new process bay . CDM will endeavor to have the contractor maintain current flows at the plant throughout construction. The primary intent of this effort is to provide Contract Documents suitable for obtam' ag construction bids (one contract) for the NCWTP. The provided Contract Documents incorporate the scope of services provided in Work Authorization No . 1 and this amendment. All Phase II improvements will be designed as requested by IRC and will be limited to improvements within the site perimeter fencing. In general the new or modified facilities under this amendment include the followingitems : PPY Ym Raw Water Supply S ste ■ Add three additional 2 . 14 mgd upper Floridian aquifer production wells (including meters, telemetry, well pumps, etc . ) .

Pretreatment System ■ Add two new 2 mgd (each) horizontal cartridge filter housings in the new process bay . ■ Add two (or one larger) new horizontal cartridge filter housings for the bypass/ blend line to replace the existing vertical cartridge filter housing. Membrane Process and Administration Building ■ Add an additional three 1 . 5 mgd permeate capacity nanofiltration skids in the new membrane processing building with local instruments and controls . ■ Add one additional Auxiliary Generator Power unit in the new electrical building sized to provide adequate power to run half of the treatment plant loads at build-out. Post-Treatment System ■ Add one additional degasifier unit, identical to existing degasifier unit, on top of the new expanded clearwell structure. ■ Add one new two-stage odor control scrubber unit to treat the off-gas from the two new degasifiers located on top of the new expanded clearwell structure . ■ Replace the existing single stage odor control scrubber with a two-stage unit. B-2 Mh208O. doc ■ Evaluate blower requirements for the new two-stage odor control scrubbers and adjust equipment accordingly . ■ Evaluate blow down rates of the two-stage odor control scrubbers and adjust the design assumptions of the blow down lift station accordingly. Bulk Chemical Storage Area/ Systems ■ Upgrade chemical metering pumps to handle all new skids being installed . ■ Evaluate piping connections in small and large piping diagrams to connect to build-out conditions . Hypochlorite System ■ Expand existing bulk storage capabilities including the installation of additional structures and tankage to the north of the existing storage building. ■ Add new bulk sodium hypochlorite storage tanks in existing structure . ■ Upgrade existing feed pumps . Instrumentation and Control System ■ Expand the existing and proposed control systems with additional I/ O cards and software to control and monitor functions of the additional process equipment specified to increase the treatment plant capacity to build-out.
