Ohio Admin. Code 3745-90-01 - [Effective until 11/1/2022] Harmful algal blooms - definitions
(A)
"Action level,"
for the purposes of this chapter, is the concentration of a cyanotoxin which,
if exceeded, will require additional monitoring, and potentially other actions
as described in this chapter of the Administrative Code.
(B)
[Reserved.]
(C)
(1)
"Cyanobacteria" means
photosynthesizing bacteria, also called blue-green algae, which naturally occur
in marine and fresh water ecosystems, and may produce cyanotoxins which at
sufficiently high concentrations can pose a risk to public health.
(2)
"Cyanobacteria screening" means quantitative polymerase chain reaction (qPCR)
for the detection of genes unique to cyanobacteria and genes associated with
the production of cyanotoxins, or a method for phytoplankton identification
acceptable to the director.
(3)
"Cyanotoxin"
means a toxin (such as microcystins) produced by cyanobacteria, which include
liver toxins, nerve toxins and skin toxins.
(D)
(1)
"Detected" or "detection" means an analytical result
that is equal to or greater than the reporting limit for the analytical method
being used.
(2)
"Distribution sampling points" means representative
points in the distribution system.
(E)
[Reserved.]
(F)
"Finished water sampling point" means each entry point
to the distribution system which is representative of the water intended for
distribution and consumption without further treatment, except as necessary to
maintain water quality in the distribution system (e.g., booster disinfection,
addition of corrosion control chemicals.)
(G)
[Reserved.]
(H)
[Reserved.]
(I)
[Reserved.]
(J)
[Reserved.]
(K)
[Reserved.]
(L)
[Reserved.]
(M)
"Microcystins" means total microcystins: the
combination of all the variants of the cyanotoxin microcystin, which is
produced by a number of cyanobacteria.
(N)
[Reserved.]
(O)
[Reserved.]
(P)
"Phytoplankton"
means free-floating photosynthesizing microscopic organisms that inhabit almost
all bodies of water, and include cyanobacteria, diatoms, green algae and
dinoflagellates.
(Q)
[Reserved.]
(R)
"Raw water
sampling point" means each plant intake in use prior to any treatment, or
another raw water sampling point acceptable to the director.
(S)
[Reserved.]
(T)
[Reserved.]
(U)
[Reserved.]
(V)
[Reserved.]
(W)
(1)
"Week" means a period of seven days beginning with
Sunday and ending with Saturday.
(2)
