Section 255.110  Containment Management and Operations

a)         Precipitation and accumulation shall never exceed a level that would impair the holding capacity of the secondary or operational area containment.  Such precipitation accumulation should be removed from the secondary and operational area containment systems after each storm.

1)         Precipitation accumulation containing agrichemicals shall be used as provided in subsection (e) or disposed of as provided in subsection (g).

2)         Precipitation accumulation from containment structures shall not be discharged from the containment area as surface runoff during the agrichemical application season, except when the following conditions are met:

A)        The containment structures have been cleaned and rinsed of agrichemicals in compliance with subsections (b) and (c).

B)        The discharge shall not cause water quality violations pursuant to 35 Ill. Adm. Code, Subtitle C, or a pesticide release pursuant to the Environmental Protection Act [415 ILCS 5].

b)         Agrichemical spills into secondary containment structures shall be recovered promptly and the structures washed to remove agrichemical contamination.

c)         Operational area containment shall be promptly cleaned and rinsed after any agrichemical spill or leakage.  The operational area containment shall also be cleaned and rinsed immediately after the termination of each agrichemical application season.  These facilities shall be washed with a biodegradable cleanser, triple rinsed with a high pressure hose and all standing water shall be removed.  Proper cleaning of the operational area containment shall include removal, washing and rinsing of material from the operational area, mud, pits, sump pits and all interconnected pipes or structures.

d)         Discharge or spills of agrichemicals, agrichemical mixtures, rinsates and wash waters outside of secondary or operational area containment shall be immediately contained, material recovered to extent possible, and the area cleaned.  Reportable agrichemical spills shall be reported immediately by telephone to the Illinois Emergency Management Agency any time during the day or night by calling 1-800-782-7860 or 1-217-782-7860.

e)         Agrichemicals, agrichemical residues, rinsates, and agrichemical contamination wash water recovered from the secondary and operational containment facilities shall be field applied at agronomic rates, used in a liquid mixing operation, or otherwise recycled or disposed of in accordance with this Part.  Any pesticide laden residues, rinsates, and pesticide contaminated wash water that are to be land applied shall be handled in accordance with the products' labels.  Field application of diluted pesticide solutions is an acceptable use if the total annual application amounts of the pesticide do not exceed the pesticide label application rates.  Rinsates and pesticide contaminated wash water may be used to make up the total spray mixture if the mixture does not exceed the pesticide label application rates.

f)         Field washing of exterior surfaces of agrichemical application equipment is acceptable at the site of the agrichemical application provided no runoff from the site occurs.

g)         Agrichemicals, agrichemical residues, rinsates, and agrichemical contaminated wash water shall not be disposed through storm sewers, sanitary sewer systems, public or private sewage treatment facilities or wells, waters of the State, nor to land, except as provided in subsections (e) and (f).

h)         Agrichemicals and agrichemical mixtures that cannot be used in accordance with the respective product's label or as set forth in this Section shall be disposed of as a special waste or hazardous waste as authorized by the Environmental Protection Act [415 ILCS 5] and 35 Ill. Adm. Code 724, 725 and 809.

i)          Empty pesticide containers shall be stored in the operational containment area or an area protected from contact with precipitation prior to disposal and such containers shall be triple rinsed or comparably cleaned (e.g., rinsed with pressure hose). Such containers shall be disposed of in accordance with the Environmental Protection Act [415 ILCS 5] and 35 Ill. Adm. Code 724 and 725.

j)          Spray application vehicles that are not cleaned as provided in subsection (f) shall be parked in the operational containment area or protected from precipitation.  Agricultural aircraft are not covered by this provision.

k)         Dry fertilizer application equipment with covered hoppers may be field cleaned by brushing the working end of the equipment to remove the fertilizer or cleaned as provided in subsection (f) or protected from precipitation.
