to the cumulative pollutant loading rates in
391-3-6-.17(5)
Table 2 is applied to the land, the applier shall contact the EPD to determine
if bulk sewage sludge subject to cumulative pollutant loading rates has been
previously applied to the site.
(i) If bulk
sewage sludge has been applied to the site and the cumulative amount of each
pollutant applied to the site is known, that amount shall subtracted from the
cumulative pollutant loading rate for each pollutant in
391-3-6-.17(5)
Table 2 to determine the additional amount of each pollutant that can be
applied to the site. For arsenic, mercury, and selenium, the cumulative amount
of each pollutant applies to the site since July 20, 1993 shall be utilized for
the calculations. For copper, lead, zinc, nickel, and cadmium the cumulative
amount of each pollution applied to the site since the first bulk sewage sludge
application shall be utilized for the calculations.
(ii) If bulk sewage sludge subject to the
cumulative pollutant loading rates in
391-3-6-.17(5)
Table 2 has been applied to the site and the cumulative amounts of pollutants
applied to the site are unknown, no additional amount of each pollutant shall
be applied to the site.
2. Before bulk sewage sludge is land applied,
the applier shall contact the EPD to determine whether bulk sewage sludge has
been previously applied to the site. If bulk sewage sludge has been previously
applied to the site, the amount of mineralized nitrogen from previous sewage
sludge applications that is available for crop uptake, as well as the amount of
nitrogen from other sources that is available for crop uptake, shall be taken
into account in determining the agronomic loading rate.
(f) When a preparer provides bulk sewage
sludge to an applier, the preparer shall provide the applier notice and
necessary information to comply with the requirements in this
subparagraph.
(g) When a preparer
provides sewage sludge to another preparer, the person who provides the sewage
sludge shall provide the person who receives the sewage sludge notice and
necessary information to comply with the requirements in this
subparagraph.
(h) The applier shall
provide the owner or lease holder of the land application site notice and
necessary information to comply with the requirements in this
subparagraph.
(i) Any person who
land applies bulk sewage sludge subject to the cumulative pollutant loading
rates in 391-3-6-.17(5)
Table 2 shall provide written notice to the EPD before the initial application
to a site, and the EPD shall retain the notice and provide access to it. The
notice shall include:
1. The location, by
either street address or latitude and longitude, of the land application
site.
2. The name, address,
telephone number, and permit number (if appropriate) of the person who will
apply the bulk sewage sludge.
(10)
Management Practices.
(a) Bulk sewage sludge shall not be applied
to the land if it is likely to adversely affect a threatened or endangered
species listed under section 4 of the Federal Endangered Species Act
(16 U.S.C. §§
1531-
1544) or its designated critical
habitat.
(b) Bulk sewage sludge
shall not be applied to an agriculture land, forest, a public contact site, or
a reclamation site that is flooded, frozen, or snow covered so that the bulk
sewage sludge enters a wetland or others waters of the State of Georgia except
as provided in a permit issued pursuant to the Georgia Water Quality Control
Act and 391-3-6-.06.
(c) Site restrictions, buffer areas, and any
additional EPD requirements shall apply to the land application of bulk sewage
sludge. Class B sewage sludge shall also be subject to the site restrictions in
391-3-6-.17(17)(c).
Reduction of buffer areas on sites where exceptional quality sludge is land
applied will be considered by the EPD upon written request. However, in no case
shall bulk sewage sludge be applied to areas located 35 feet or less from
waters of the State of Georgia.
(d)
Bulk sewage sludge shall not land applied at greater than agronomic rates
except on reclamation sites. Agronomic rates shall be calculated using the
sludge application rate determination procedures as determined by the EPD. The
application rate for sewage sludge on reclamation sites shall be determined on
a case-by-case basis.
(e) Sewage
sludge that is sold or given away in a bag or other container for land
application shall have a label affixed to the bag or other container or an
information sheet shall be provided to the person who receives the sewage
sludge. The label or information sheet shall contain the following information.
1. The name and address of the person who
prepared the sewage sludge.
2. A
statement that application of the sewage sludge to the land is prohibited
except in accordance with the instructions on the label or information
sheet.
3. The annual sludge
application rate that does not cause any of the annual pollutant loading rates
in 391-3-6-.17(5)
Table 4 to be exceeded.
(f) Under no conditions may sewage sludge be
stockpiled at a land application site.
(11)
Monitoring.
(a) The pollutants listed in
391-3-6-.17(5), the
pathogen density requirements listed in
391-3-6-.17(7) and
the vector attraction reduction requirements listed in
391-3-6-.17(8)(a) through
(8)(h), and any additional parameters
contained in the permit, shall be monitored at the frequency listed in Table 5.
Table 5 -- Monitoring Frequency
Amount of Sewage Sludge (dry
tons/year)* |
Frequency |
0 - 300 |
once/year |
300 - 1600 |
once/quarter |
1600 - 16000 |
once/two months |
16000 or greater |
once/month |
*The "amount of sewage sludge" refers to either the amount of
bulk sewage sludge (dry weight) applied to the land or the amount of sewage
sludge (dry weight) received by a preparer that sells or otherwise distributes
sewage sludge in a bag or other container for application to the land.
(b) After the sewage sludge has
been monitored at the frequency in Table 5 for two years, the EPD may reduce
the monitoring frequency for the pollutants listed in
391-3-6-.17(5). In
no case shall the monitoring frequency be less than once per year.
(12)
Analytical
Methods. Representative sewage sludge samples shall be analyzed in
accordance with the methods contained in
40 CFR
503.8. Test methods used to determine
toxicity, such as the Toxicity Characteristic Leachate Procedure, may be used
to determine whether sewage sludge is hazardous, but shall not be used for the
purpose of determining compliance with any of the inorganic pollutant
requirements contained in this rule.
(13)
Recordkeeping.
(a) Persons who prepare bulk sewage sludge
for land application or who sell or give away sewage sludge in a bag or other
container, shall develop the following information and retain it for five

governing authority in which a land application site is located may assess the
generator of the sewage sludge and the owner of the land application site
reasonable fees for environmental monitoring of the site and may hire persons
to monitor the site. The assessed fee shall be limited to charges incurred for
monitoring those parameters contained in the approved sludge management plan
and the permit. Payment of the assessed fee shall be made prior to the
application of sewage sludge. Failure to pay such fees, if assessed, shall be
grounds for the local governing authority to seek an injunction to stop the
land application of sewage sludge.
