3SpecificChallengestoIndustry:
Current biosolids management not sustainable:
20% projected population increase by 2030
Limited landfill capacity
Longer hauling distances
Increasing costs (current range $45-$90 per wet ton)
State and Federal Regulations:
Increasing restrictions on current practices land application and ADC
Local Restrictions:
Solano County Ordinance
San Joaquin AQMD Rule 4565 (Biosolids eliminated as ADC; incorporation within 3 hours currently 24 hours)
