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).
