   2 Remember that some TSS reduction occurs in a functioning septic tank by allowing settling and digestion of wastes (see Module 1 for details).

   3If wastewater has 1,000,000 fecal coliform/100 ml, a 1 or 2 log reduction would reduce these numbers to 100, 000 or 10,000 fecal coliform/100 ml respectively.

   4BCDHE is presently conducting research on various alternative onsite septic system to test their ability to remove viruses under a 319(b) Grant from DEP.

   5This standard is somewhat subjective, but lies between the drinking water standard of 1 total coliform/100 ml, and the shellfish water standard of 70 total coliform/100 ml.

   6Less common situations where alternatives may be used for new construction or increased flows include projects that have access to a municipal sewer and sites owner or controlled by and agency of the feceral government, subject to approval by DEP.

   7The Health Agent or Board of Health should insist on seeing and reviewing the approval letter that is issued with the technologies' approvals.

   8Systems designed in conformance with the old (1978)Title5 or systems installed prior to the 1978 Code.

   9Several other technologies -- Amphidrome, Waterloo biofilter--which are in the early stages of the DEP approval process are seeking further reductions in leaching field size, up to a reduction of 67% or loading rates as high as 5 gal/sf/day, and are seeking to be allowed to install these systems for new construction.

   10Pressure Dosing is required under most of the remedial use approvals. Boards of Health should check the special conditions for approval that are outlined in the approval letters for each technology.

   11If not already required in the DEP approval conditions.

   12Again, pressure dosing may be required as part of a technology approval. Boards of Health should check the special conditions in the DEP approval letter.

   13Title 5 implies that there is(will be) a process by which nitrogen sensitive areas will be formally recognized in the Code (See Section 15.215(2).
