Section 259.330  Final Assessment

a)         The purposes of the final assessment are to execute the sampling and analysis plan for the soil and/or groundwater at the site and determine the locations of the agrichemical concentrations that are:

1)         greater than or equal to the RSDLs,

2)         greater than or equal to the SCOs, and

3)         below the RSDLs and SCOs.

b)         The final site assessment shall provide:

1)         results of laboratory analyses or field screening measurements of agrichemical concentrations in soil and groundwater, including quality control samples;

2)         facility site maps, at a scale no larger than 1 inch equals 200 feet, of sufficient detail and accuracy to show all of the following:

A)        the locations of all soil samples, keyed to a table of analytical results,

B)        the locations of any monitoring or water supply wells sampled, keyed to a table of analytical results,

C)        the direction and rate of movement of agrichemicals in groundwater, if known,

D)        areas of the site that involve the storage or mixing and loading of agrichemicals,

E)        site structures or buildings,

F)         roads or driveways and parking facilities,

G)        the location of the potable water supply for the site and any groundwater monitoring wells on the site, and

H)        the map scale (graphic and nominal), north arrow, date, name and address of preparer, and location of the site with respect to section, township, range, and principal meridian;

3)         characterization of significant physical features of the facility and vicinity that may affect agrichemical fate and transport and risk to potable wells and Class I, Class II or Class III groundwater.

c)         The applicant shall inform the Department of the schedule for conducting the final site assessment to allow representatives of the Department to observe assessment activities.
