How it Works

The BioMicrobics FAST® systems provide significantly improved nitrification/denitrification performance over traditional systems and exceeding typical effluent requirements for wastewater recycling opportunities or reducing the size of the leach field with less aesthetic disturbance of property value or system components. Offering versatility and consistent high performance, the FAST® are also a favorite on marine vessels and offshore platforms of all types to produce high-quality effluent, specifically designed for extreme environments.

How it Installs

Using MicroFAST® Systems solves most onsite wastewater treatment issues.  With a small footprint, the MicroFAST system is integrated into a standard septic tank and does not require additional space. Naturally, the MicroFAST® offers higher levels of nitrogen removal (NSF/ANSI 245). With the SFR® feature, intermittent operation of the blower reduces electricity usage up to 45% and can provide improved nitrogen performance (in specific situations).

About Environmental Plans

Environmental Plans (E-Plan) are prepared for facilities to provide full reports for each of the below required plans. An E-Plan can consist of the below primary components:

  • The Storm Water Pollution Prevention Plan (SWPPP) is in accordance with requirements of USEPA’s NDPES General Permit Program for Storm Water Discharges Associated with Industrial Activity, and Virginia’s General Permit. The SWPPP identifies potential sources of pollution that may reasonably be expected to affect the quality of storm water discharge from the facility. In addition, the plan describes and ensures the implementation of practices that will be used to reduce the pollutants in storm water discharges from the facility and assures compliance with the terms of the issued general permit.
  • The Storm Water Monitoring Plan (SWMP) represents requirements applicable in Virginia’s General Permit. Typically, this plan is a subsection of the SWPPP, however, for ease of access and to provide convenience for monitoring this plan has been prepared to be a stand-alone document.
  • The Spill Response & Cleanup Plan (SR&CP) is typically a part of the SPCC plan. However, it has been prepared as a stand-alone document in case the facility is not required to prepare a SPCC plan.
  • The Spill Prevention, Control and Countermeasures (SPCC) Plan is required by the EPA’s Oil Pollution Prevention Rule, Title 40, Code of Federal Regulations, Part 112 (40CFR 112) when a facility meets three criteria: 1) it must be non-transportation related; 2) it must have an aggregate aboveground oil storage capacity greater than 1,320 gallons or a completely buried oil storage capacity greater than 42,000 gallons; 3) there must be a reasonable expectation of a discharge into or upon navigable waters of the United States or adjoining shorelines. Preparation of the SPCC is the responsibility of the facility owner or operator but must be certified by a Professional Engineer if the facility has an aggregate aboveground oil storage capacity greater than 10,000 gallons.

The E-Plans must be amended whenever there is a change in facility design, construction, operation or maintenance that has a significant effect on the potential for the discharge of pollutants to surface waters. The E-Plan also must also be revised if it proves to be ineffective in eliminating or significantly minimizing pollutants from the sources identified.
