Policies and Programs
Forest ConservationCecil County’s Board of County
Commissioners Retention of existing forestry
No change!
Changes must align with the Code of Maryland Natural Resource Policies
Maintain the natural resources of Cecil
County
Water Quality ControlMaryland Department of Agriculture
Implementation of licenses, approvals and permits to reduce the negative impact from land cultivation and other agricultural activities on water quality
Farmers must abide because of soil erosion into the Bay
Consumer ConfidenceMaryland Department of Agriculture
Animal Health Program Provide safe foodAnimal disease controlIncreased the enforcement of livestock inspection
Food Quality Assurance ProgramAudits and inspections Good Agricultural Practices (GAP) Good Handling Practices (GHP)Grade analysis of eggsDecrease their use of pesticides
StormwaterMaryland Department of the Environment
Control the erosion and sediment runoff
Use rain as resource
The Stormwater Management Act of 2007 required BMP be used by all current and future development activities

Sector Analysis
Cecil County Agricultural SectorCecil county is a predominantly
rural/agricultural area.Large dairy cow/beef cattle farms
are common.77% of nitrogen and 95% of
phosphorus pollution in this area can be attributed to agriculture.
Northeast River Advanced WWTP(NERAWWTP) Upgrade
MDE mandated that all large WWTPs be upgraded to Enhanced Nutrient Removal(ENR) by Dec. 2016
NERAWWTP is the only WWTP in Cecil County requiring an upgrade.
Previous treatment level: Biological Nutrient Removal(BNR)
Expected project cost: $40 million.
Biological versus Enhanced Nutrient Removal
ENR utilizes a process known as a Membrane Bioreactor(MBR).
Higher initial cost than alternatives, but benefits include:
Higher water treatment level than alternatives
Cost of future expansions is lower than other alternatives.
Nutrient Reduction Levels
Nutrient Biological Nutrient Removal
Enhanced Nutrient Removal
Nitrogen 8 mg/L to 10 mg/L
~3 mg/L
