     (a) The following quantitative medications are permissible in test samples up to the stated concentrations:

     Acepromazine - 25 ng/ml urine

     Albuterol - 1 ng/ml urine

     Benzocaine - 50 ng/ml urine

     Bupivacaine - 5 ng/ml urine

     Betamethansone - 60 ng/ml urine

     Clenbuterol - 25 pg/ml serum or plasma

     Dexamethasone - 1.5 ng/ml serum or plasma

     Diclofenac - 5 ng/ml serum or plasma

     DMSO - 10 mc/ml serum or plasma

     Firocoxib - 40 ng/ml serum or plasma

     Glycopyrrolate - 3.5 pg/ml serum or plasma

     Lidocaine - 50 ng/ml urine

     Mepivacaine - 10 ng/ml urine

     Methocarbamol - 1 ng/ml serum or plasma

     Methylprednisolone - 1.3 ng/ml serum or plasma

     Prednisolone - 2 ng/ml serum or plasma

     Procaine - 25 ng/ml urine

     Promazine - 25 ng/ml urine

     Pyrilamine - 50 ng/ml urine

     Salicylates - 750,000 ng/ml urine

     Theobromine - 2000 ng/ml urine

     Triamcinolone acetonide - 1 ng/ml serum or plasma

     (b) The official urine or blood test sample may not contain more than one of the above substances, including their metabolites or analogs, and may not exceed the concentrations established in this rule.

     (2) Environmental substances.

     (a) Certain substances can be considered "environmental" 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 or exposure during the cultivation, processing, treatment, storage, or transportation phases. Certain drugs are recognized as substances of human use and could therefore be found in a horse. The following substances are permissible in test samples up to the stated concentrations:

     Caffeine - 100 ng/ml serum or plasma

     Benzoylecgonine - 50 ng/ml urine

     Morphine Glucuronides - 50 ng/ml urine

     (b) If a preponderance of evidence presented shows that a positive test is the result of environmental substance or inadvertent exposure due to human drug use, that evidence should be considered as a mitigating factor in any disciplinary action taken against the trainer.

     (3) Androgenic-anabolic steroids.

     (a) The following androgenic-anabolic steroids are permissible in test samples up to the stated concentrations:

     Stanozolol (Winstrol) - 1 ng/ml urine in all horses regardless of sex.

     Boldenone (Equipoise) - 15 ng/ml urine in intact males. No level is permitted in geldings, fillies or mares.

     Nandrolone (Durabolin) - 1 ng/ml urine in geldings, fillies, and mares, and for nandrolone metabolite (5a-oestrane-3&bgr;,17a-diol) - 45 ng/ml urine in intact males.

     Testosterone - 20 ng/ml urine in geldings. 55 ng/ml urine in fillies and mares. Samples from intact males will not be tested for the presence of testosterone.

     (b) All other androgenic-anabolic steroids are prohibited in race horses.
