Comments: No Daphnia magna monitoring results were provided for the month of January. Daphnia magna monitoring tests must be done on each effluent aliquot collected for acute lethality testing. No arsenic test results were provided for the months of May, June, August, September, November and December. Regular (weekly) testing is required if a substance's monthly mean concentration is equal to or greater than 10% of the maximum authorized monthly mean concentration.

Notes:
ND: No Deposit
NMR: No Measurement Required
Pass: ≤50% Mortality
Fail: >50% Mortality
Highlighted data indicate that a monthly effluent quality standard was exceeded for that month.
A "Pass" for the Daphnia magna monitoring test is not a requirement.
