Additional Precautions
Section 391
Section 391.440 Additional
Precautions
a) If the requirements of Subpart D cannot be met, additional
environmental precautions such as groundwater monitoring, soil analyses, plant
tissue sampling and analysis shall be included as permit conditions as
necessary to assure compliance with the Environmental Protection Act and 35
Ill. Adm. Code, Subtitle C, Subchapter l.
b) If groundwater monitoring is required, a minimum of 3
saturated zone groundwater monitoring wells (1 upgradient and 2 downgradient)
shall be provided at each land application site. Additional wells may be
required depending upon the size of the site, hydrogeology, direction of
groundwater movement, sludge quality and other considerations.
1) The design, construction and operation of the groundwater
monitoring system shall be done in accordance with the regulations adopted
pursuant to Title V of the Act and policies of the Division of Land Pollution
Control.
2) The location of groundwater monitoring wells is site specific
and the hydrogeology of the particular site shall be considered in the design.
3) The wells must be sampled monthly and analyzed for parameters
including, but not limited to, nitrates, electrical conductivity, chlorides,
pH, hardness and heavy metals.
c) Yearly plant tissue sampling and analysis may also be required
to determine the uptake characteristics and heavy metal concentrations of the
plant tissue and grain. Plant tissue sampling and analyses shall be the
responsibility of the generator and of those utilizing the sludge.
d) The plant tissue monitoring and groundwater monitoring results
of Subsections b and c will be reviewed by the Agency to determine future
controls and frequency of monitoring.
