Sec. 7.

(a) Except as approved by the commissioner under subdivision (4), the amount of septage to be applied must not exceed the following:

(1) For a soil phosphorus concentration of fifty (50) parts per million or less, the annual application rate for septage based on the nitrogen requirement of the crop grown on the land application site must not exceed the following:
(A) Fifty-three thousand (53,000) gallons per acre based on a corn crop grown during the next growing season.

(B) Thirty-eight thousand (38,000) gallons per acre based on an alfalfa, soybean, wheat, or hay crop grown during the next growing season.

(C) Nineteen thousand (19,000) gallons per acre based on land that is grass, pasture, or set aside for continued growth during the current growing season.

(2) For a soil phosphorus concentration of between fifty-one (51) and one hundred (100) parts per million, the annual application rate for septage based on the phosphorus removal rate of the crop grown on the land application site must not exceed the following:
(A) Twelve thousand (12,000) gallons per acre based on a corn crop grown on the site during the next growing season.

(B) Nine thousand (9,000) gallons per acre based on a soybean crop grown during the next growing season.

(C) Ten thousand four hundred (10,400) gallons per acre based on a wheat crop grown during the next growing season.

(D) Thirteen thousand (13,000) gallons per acre based on an alfalfa crop grown during the current growing season.

(E) Eleven thousand two hundred (11,200) gallons per acre based on grass, pasture, or a hay crop grown in the current growing season.

(3) For a soil phosphorus concentration of between one hundred one (101) and two hundred (200) parts per million, the annual application rate for septage based on the phosphorus removal rate of the crop grown on the land application site must not exceed the following:
(A) Eight thousand (8,000) gallons per acre based on a corn crop grown during the next growing season.

(B) Six thousand (6,000) gallons per acre based on a soybean crop grown during the next growing season.

(C) Seven thousand (7,000) gallons per acre based on a wheat crop grown during the next growing season.

(D) Eight thousand seven hundred (8,700) gallons per acre based on an alfalfa crop grown during the current growing season.

(E) Seven thousand five hundred (7,500) gallons per acre based on grass, pasture, or a hay crop grown during the current growing season.

(F) Land application is prohibited on set aside land.

(4) The commissioner may approve alternative annual nutrient application rates proposed in the permit application based on site-specific harvest records or the crop removal rates:
(A) when harvest records indicate the need for a higher application rate than specified in subdivisions (1) through (3); or

(B) for a crop where no maximum rate is specified in subdivisions (1) through (3).

(5) Annual nitrogen application rates are determined using the following formula:

AAR = N

0.0026

Where: AAR means annual application rate

N means crop nitrogen requirement

(6) Application rates limited by the soil phosphorus concentration are determined using one (1) of the following formulas:
(A) For subdivision (2), the following formula:

CRR x Y x 1.5

0.00478

Where: CRR means crop removal rate (amount of phosphorus removed by the crop) based on the crop removal rates published in the Natural Resources Conservation Service, Conservation Practice Standard, Nutrient Management, Code 590*, October 2013.

Y means crop yield

(B) For subdivision (3), the following formula:

CRR x Y x 1.0

0.00478

Where: CRR means crop removal rate (amount of phosphorus removed by the crop) based on the crop removal rates published in the Natural Resources Conservation Service, Conservation Practice Standard, Nutrient Management, Code 590*, October 2013.

Y means yield

(7) The maximum annual rate for grease must not exceed ten thousand (10,000) gallons per acre.

(8) When two hundred thousand (200,000) gallons per acre of septage have been applied to a site, the person land applying septage shall cease land application until the following actions haven [sic] been taken:
(A) The person land applying septage shall collect representative soil samples and have them analyzed for the following parameters:
(i) Arsenic.

(ii) Cadmium.

(iii) Copper.

(iv) Lead.

(v) Mercury.

(vi) Molybdenum.

(vii) Nickel.

(viii) Selenium.

(ix) Zinc.

(x) PCBs.

(B) The person land applying septage shall submit the results of the soil test to the department with a request to resume land application at the site.

(C) The commissioner shall:
(i) review the test results to determine whether land application may continue at the site; and

(ii) notify the person land applying septage with a decision on whether land application may resume.

(9) After two hundred thousand (200,000) gallons per acre of septage have been applied to a site, for each subsequent septage management permit application that requests approval for land application of septage at the site, the person land applying septage shall:
(A) conduct soil sampling as required in subdivision (8); and

(B) submit the results to the commissioner.

(10) The operator must keep an operating record of the amount of septage applied that is:
(A) updated each application day;

(B) located at the permitted septage management business address; and

(C) made available to representatives of the commissioner during normal business hours for inspection.

(b) All soil tests must:

(A) consist of one (1) composite sample per every twenty (20) acres, with each composite consisting of twenty (20) representative subsamples;

(B) be analyzed for pH; and

(C) be analyzed by a laboratory certified by The North American Proficiency Testing (NAPT) Program.

(c) For each day that septage is land applied the operator must record and retain for five (5) years the following information:

(1) Business name.

(2) Business permit number identified in the permit.

(3) The site identification number identified in the permit.

(4) A map identifying the area of the site where septage was applied.

(5) The date septage was applied to each site.

(6) The volume, in gallons, of septage that was applied to each site.

(7) Whether the type of septage applied was domestic septage, grease, or a combination of domestic septage and grease.

(8) Method of application.

(9) Number of acres used.

(10) The projected crop or site use, if no crop is grown.

This determination has been made under my direction and supervision in accordance with the system designed to ensure that qualified personnel properly gather and evaluate the information used to determine that the pathogen requirements and vector attraction reduction requirements have been met. I am aware that there are significant penalties for false certification including the possibility of fine and imprisonment.".

(d) The owner or permittee shall submit a quarterly report to the department concerning land application of septage as follows:

(1) The report must be submitted on a form provided by the department.
