(J)(7) of this rule, the location of the
land application area shall maintain
the minimum isolation distances in table J-1 of this rule. The
director may
reduce the isolation distance requirements where class A
treated sewage
or liquid industrial waste
is land applied. The
director may increase isolation distance requirements to protect public health
or the environment.

(2) In
addition to the requirements of paragraphs (C) and (J)(1) of this rule, no
person shall land apply class A
treated sewage or
liquid industrial waste as follows:
(a)
Except at Ohio EPA approved unrestricted or Ohio EPA approved restricted access
sites;
.
(b)
Within fifty feet from an occupied building;
.
(c) Within the sanitary isolation radius for
a
public water system well, as determined in accordance with rule
3745-9-04 of the Administrative
Code
;
.
(d)
Within the inner management zone of a source water protection area (one-year
time-of-travel area) for a community or non-transient, non-community public
water system using ground water or within three hundred feet of any public
water system well; and
.
(e)
Within drinking water source protection area for a community or non-transient,
non-community public water system using ground water determined to be highly
susceptible to contamination unless additional engineering controls are
installed sufficient to protect the ground water and ground water monitoring is
performed in accordance with paragraph (L) of this rule, between the land
application system and the public water system well(s)
well.
(3) In addition to
the requirements in paragraphs (C), (J)(1)
, and (J)(2)(c) to(J)(2)(e) of this rule, no
person
shall land apply class B
treated sewage or liquid
industrial waste as follows:
(a) Except
at Ohio EPA approved restricted access sites;
.
(b) At any site that contains sand and gravel
as the predominant natural material within five vertical feet of natural
grade;
.
(c)
Within two hundred feet from an occupied building;
.
(d) Within fifty feet of developed springs,
karsts, sinkholes, drainage ways, subsurface tiles with surface openings,
surface water bodies, and road right-of-ways;
.
(e) On sodded fields and forested areas with
slopes greater than twelve per cent unless measures able to control runoff
approved by the director, such as berms, collection ditches or check dams, are
installed; and
.
(f) On
fields with slopes greater than eight per cent unless the detailed engineering
plans and specifications required by paragraph (F) of this rule include runoff
control measures that demonstrate to the director runoff will not impact
surface waters of the state.
(4) In addition to the requirements in paragraphs (C), (J)(1),
(J)(2)(c) to (J)(2)(e), and (J)(3)(b) to
(J)(3)(f) of this rule, no person shall land apply class C treated sewage
or liquid industrial waste
except at Ohio EPA
approved sites.
(5) The siting
criteria and the isolation distance requirements of this paragraph shall not
apply to occupied buildings if the
person who will land apply
treated sewage
or liquid industrial waste
obtains a
land
application contract from each owner of a neighboring
occupied building located
within the siting distances set forth in this rule and includes a copy of the
land application contract with the permit to
install application. The
land
application contract shall state that:
(a) The
owner of the occupied building is aware of the proposed land application;
.
(b) The owner of the occupied building has no
objection to the land application at a location not otherwise allowed by the
isolation distance requirements and siting criteria in this rule; and
.
(c) The
land application occurs between dusk
and dawn and the
land application system utilizes low head sprinklers or an
equivalent low-exposure distribution method.
[Comment: Night time or early morning land application usually
reduces the risk of people coming into direct contact with the treated sewage
or liquid industrial waste
. Strict night time
application is sometimes impractical and daytime application helps to reduce
spills and over-application that might result from not being able to see the
land application take place.]
(6) The director may reduce the isolation
distance requirements to a property line if a land application contract from
each property owner within the fifty-foot isolation distance is submitted as
part of the permit to install application and treated sewage
or liquid industrial waste
is applied from dusk
until dawn with low head sprinklers, or with an equivalent low-exposure
distribution method. The land application contract shall state that these
property owners are aware of, and have no objection to, the proposed land
application of treated sewage or liquid industrial
waste
within fifty feet of their property lines.
(7) If class A treated sewage
or liquid industrial waste
requirements for
effluent limits and monitoring requirements in table K-2 of this rule are met,
the director may reduce the isolation distance restrictions established in this
rule provided the applicant can demonstrate to the director that the potential
for negative impacts to human health or waters of the state does not
exist.
(K) Land
application systems: treatment requirements, effluent water quality and
monitoring requirements.
(1) A land
application system shall be designed in accordance with table K-1 of this rule
and shall have a land application management plan that contains effluent
limits, which are developed and monitored in accordance with table K-1 of this
rule. The director may require sampling and monitoring of pollutants not listed
in tables K-2 to K-5 of this rule, to protect public health or the environment.
The director may require treated sewage or liquid
industrial waste
that will be land applied to a golf course or athletic
field to meet class A treated sewage or liquid
industrial waste
requirements in accordance with table K-2 of this
rule.
(2) In addition to paragraph
(K)(1) of this rule, any
land application system that will discharge to
waters
of the state shall have an approved
NPDES permit that contains, where
applicable, internal and final effluent limits
where
as follows:
(a) The internal limits shall
:
be developed and
monitored in accordance with table K-1 of this rule and be applied at the point
the effluent leaves the treatment works, prior to storage, or prior to land
application if no storage is provided.
(i) Be developed and monitored in
accordance with table K-1 of this rule; and
(ii) Be applied at the point the
effluent leaves the treatment works, prior to storage, or prior to land
application if no storage is provided; and
(b) The final effluent limits shall be
developed in accordance with best available demonstrated control technology
criteria, as set forth in table 5-1 of rule
3745-1-05 of the Administrative
Code or water quality based effluent limits in accordance with Chapter 3745-1
of the Administrative Code, whichever is more stringent.

Effluent disinfection is not directly required; however, the entity is required
to meet all applicable discharge permit limits. If disinfection facilities
exist, they need to be maintained in an operable condition. Any design of
wastewater treatment works should provide for the capability to install
disinfection if required at a future time. Disinfection may be required if
bacteriological studies or emergency conditions indicate the need.
4 Calculations for (lie
demonstrative nitrogen balance (i.e., nitrate-nitrogen available for leaching)
are not required to be submitted if the application rate is designed to be
<= 12 inches/acre/year.
5 All wastewater treatment
works shall use E. coli as the indicator organism unless fecal coliform is
specified by their existing NPDES permit.
6 Class C sewage shall
only be land applied at times set forth in an approved land application
management plan (i.e., times of the day that will minimize human exposure to
the application of the treated sewage, such as early morning between 4 a.m. and
9 a.m.).

activities;
.
(c) When
the proposed land application area is a golf course, be taken prior to the
construction of any tee boxes, fairways and greens;
.
(d) For any land application area, be done to
a minimum depth of thirty inches below natural grade. To protect public health
or the environment, the director may require deeper soil probes, soil pits or
soil borings. In areas where glacial till and fractured bedrock substratum
soils are in close proximity, the soil investigation shall be done to a depth
of at least fifty inches or until bedrock is encountered; and
.
(e) For any
storage facility or
lagoon, be
done to a minimum depth of fifteen feet below the proposed bottom of the
recompacted clay liner
;
.
[Comment: The county soil maps are at a
scale for larger systems and for land use planning purposes. A more detailed
map should be developed for land application systems so that all the included
soils can be delineated, characterized, and avoided, if necessary. The Ohio
state university extension bulletin number 905, "Soil and Site Evaluation for
Onsite Wastewater Treatment", demonstrates an acceptable procedure for
developing soil maps.]
(4) Based on the information in the general
soil survey, published loading rate tables, and the data from any soil borings,
identify the permeability and thickness of
the
following:
(a) The most permeable layer
of the soil mantle at each soil probe, soil pit or soil boring location; and
.
(b) The least permeable layer of the soil
mantle at each soil probe, soil pit or soil boring location;
.
(5) Identify the vertical separation distance
between the natural grade and all of the following conditions:
(a) Bedrock;
.
(b) Sand and gravel lenses;
.
(c)
Dense glacial till; and
.
(d)
Ground water, including any seasonal high ground water or perched water
table; and
.
(6) Discuss the site topography, including
the following:
(a) The site slope;
.
(b) The site vegetative cover;
.
(c) Any drainage ways and waterways within,
below or bordering the land application system;
and
.
(d) Any impervious surfaces.
(O) Record keeping,
reporting requirements, compliance, enforcement, and oversight.
(1) Record keeping.
(a)
Records shall be
maintained on forms provided by or approved by the director.
(a)
(b)
Upon request by the
director or
his
the director's authorized representative, any
person
shall make available, within a reasonable time for inspection and copying, all
records pertaining to the
land application system, including
the following:
(i) Pollutant sampling records;
.
(ii) Inflow and outflow monitoring
records; and
.
(iii)
Storage impoundment monitoring records for freeboard and the number of days of
remaining storage.
(b)
(c) Any person who
owns a land application system shall maintain all sampling and monitoring
records at the treatment works for at least five years. These records shall be
made available to Ohio EPA, upon request.
(2) Reporting requirements.
(a) The director shall be notified in writing
within seven days of any person discovering noncompliance with a land
application management plan or an NPDES permit.
(b) The director shall be notified at least
six months prior to the expiration date of a land application
contract.
(3)
Compliance, enforcement and oversight.
(a) The
director may deny any land application management plan application not in
compliance with this chapter and require the submittal of a new land
application management plan application, including all applicable fees, to be
submitted to Ohio EPA within thirty days.
(b)
The director may
revoke approval of any land application management plan, where the land
application system is de-commissioned or a proposed land application system is
never built.
(b)
(c) The director may revoke approval of any land application management plan not
in compliance with this chapter.
(c)
(d) A land application
system shall maintain compliance with effluent limits in the land application
management plan or NPDES permit at the point the effluent leaves the treatment
works, prior to storage, or prior to land application, if no storage is
provided.
(d)
(e) The
director may require sampling and monitoring
for pollutants at any drain tile outfall, including
sampling for
but not limited
to the following:
(i) CBOD
5;
.
(ii)
Total suspended solids;
.
(iii)
Fecal coliform bacteria
E. coli; or
.
(iv)
Total inorganic nitrogen
(v)
Total phosphorus.
