SUBJECT: Documentation for Change Order No. 3 Schedule Extension
DATE: August 6, 2012
PROJECT: Former Riverside Wastewater Treatment Plant Digester Project
The following portions of the project have resulted in additional time to date for the specified project:
Digester#8—Sludee Disposal at CSC Landfill
4/5/12—Republic Services approved waste characterization profile for Digester#8 sludge.
4/10/12—AUl delivered one truckload of Digester#8 sludge to CSC Landfill. Landfill indicated too much
free-liquid in truck. Hauling was halted.
5/29/12-Republic Services onsite to perform paint filter test.Samples passed test.
6/4/12 - ALII resumed hauling of Digester #8 sludge to CSC Landfill. Landfill restricted AUl to two
truckloads per day.
6/5/12--CSC Landfill called meeting to discuss moisture content of Digester#8 sludge arriving at landfill.
AUl halted hauling of Digester #8 sludge. Even though sludge passed the paint filter test, the landfill
could not accept it due to its consistency, which prevented them from being able to cover it with heavy
equipment.
6/21/12 — AUl resumed hauling of Digester #8 sludge to CSC Landfill and continued hauling through
7/19/12.Sawdust and cement slag was used to further solidify the materials.
Total additional time to date=55 days during first halt+ 16 days during second halt= 71 days
Digester#7-Dewatering and Treatment of Liquids
4/25/12 to 4/30/12 — Pumped, treated, and discharged 41,160 gallons (2 treated tanks) from Control
Room between Digesters#8 and#9.
4/30/12 --5/30/12 — Pumped, treated, and discharged 409,576 gallons (20 treated tanks) from Control
Room between Digesters#6 and#7 and the Pump House.
Note: Current contract includes 2,800,000 gallons (approximately 140 treated tanks of liquids). The
process requires on average 5 days to process each tank(treat,fill,sample, analysis, and discharge).
Total additional time to date for treatment of liquids from other structures= 29 days
