Sec. 9.
(a) Substances described in subsection (b) are recognized as either:
(1) environmental containments
[sic] in that they are endogenous to the horse or that they
can arise from plants traditionally grazed or harvested as equine feed or are
present in equine feed because of contamination during cultivation, processing,
treatment, storage, or transportation phases; or
(2) substances of human use and addiction and
which could be found in the horse due to its close association with
humans.
(b) Regulatory thresholds have been set for the following substances:
(1) Arsenic - not to exceed three-tenths
(0.3) micrograms per milliliter total arsenic in urine.
(2) Caffeine - not to exceed one hundred
(100) nanograms per milliliter of caffeine in serum or plasma.
(3) Cobalt - not to exceed twenty-five (25)
parts per billion of cobalt in serum or plasma. A sample from a horse tested
and found by the commission's primary lab to have cobalt in excess of this
threshold shall be placed and remain on the veterinarian's list until the
concentration of cobalt in serum or plasma has fallen below the designated
threshold, or until the conclusion of the race meet. However, horses testing at
a concentration of one hundred (100) parts per billion shall be placed on the
veterinarian's list for a minimum of thirty (30) days.
(4) Estranediol - not to exceed forty-five
one-thousandths (.045) micrograms per milliliter of free plus conjugated
5[ALPHA]-estrane-3[BETA],17[ALPHA]-diol, in the urine of male horses other than
geldings.
(5) Gamma aminobutyric
acid (GABA) - not to exceed one hundred and ten (110) nanograms per milliliter
in serum or plasma.
(6)
Hydrocortisone - not to exceed one (1) microgram per milliliter of
hydrocortisone in urine.

Methoxytyramine - not to exceed four (4) micrograms per milliliter of free plus
conjugated methoxytyramine in urine.
(8) Salicylate and salicylate acid - not to
exceed seven hundred fifty (750) micrograms per milliliter of salicylate and
salicylate acid in urine or six and one-half (6.5) micrograms per milliliter of
salicylate and salicylate acid in serum or plasma.
(9) Theobromine - not to exceed two (2)
micrograms per milliliter of theobromine in urine or three-tenths (0.3)
micrograms per milliliter in serum or plasma.
(c) If the preponderance of evidence presented in the hearing shows that a positive test is the result of environmental contamination or inadvertent exposure due to human drug use it should be considered as a mitigating factor in any disciplinary action taken against the affected trainer.
