Notes (Discharge Limitations Table):

1. Samples shall be taken within one hour of the start of the discharge during storm events.

2. In the event that this outfall is used,the Nevada Division of Environmental Protection shall be notified during the first occurring normal business hours.

3. For each sample event, formula terms contained in A and B below shall have the following meaning: pH and T are field measurements of facility discharge taken at the same time and location as the water sample destined for the laboratory analysis of ammonia.

A. The chronic criteria of water quality with regard to the concentration of total ammonia are subject to the following:

(a) The facility discharge Monthly chronic concentration of total ammonia, in milligrams of nitrogen per liter, shall be calculated by the NAC 445A.118 Table 2 chronic concentration by value from table matrix of temperature and pH or by formula for the 30-Day average for each discharge sample event as described in NAC 445A.118.

(b) The concentration of total ammonia, in milligrams of nitrogen per liter, expressed as a 30-day average must not exceed the applicable chronic criterion as calculated more than once every 3 years on average and the highest 4-day average within the 30-day period must not exceed 2.5 times the applicable chronic criterion.

Measurement frequency of once per 30-day (Monthly) is an acceptable indicator for evaluating total ammonia chronic criterion and may be used in reporting to demonstrate compliance of discharge event calculated limit. However, if a sample analysis exceeds the allowed calculated chronic limit in part (a), the measurement frequency must be increased to a minimum of 4 consecutive days within the 30-day period so that chronic criterion part (b) can be applied for determining permit compliance.

B. The acute criteria for water quality with regard to the concentration of total ammonia are subject to the following:

(a) The facility discharge Daily Maximum acute concentration of total ammonia, in milligrams of nitrogen per liter, for cold water fisheries shall be calculated by the NAC 445A.118 Table 1 acute concentration by value from table matrix of pH and fishery water type or by formula for the 1-hour average for each sample event as described in NAC 445A.118.

(b) The concentration of total ammonia, in milligrams of nitrogen per liter, must not exceed the applicable acute criterion as calculated more than once every 3 years on average.

Measurement frequency for evaluating total ammonia acute criterion as daily maximum shall utilize the same measurement frequency required for that of evaluating the chronic criteria of water quality defined in A above. The total ammonia concentration determined by laboratory analysis for each sample event shall be compared to the same event’s calculated acute criterion limit

4. Divide the discharge sample result by the limit as determined from footnote 3.

The following types of wastewater discharges are covered by this permit: domestic wastewater; boiler blow-down water; and treated explosive destruct water.

A.2. EFFLUENT LIMITATIONS

A.2.1. There shall be no discharge from the facility except as authorized by this permit.

A.2.2. There shall be no discharge of substances that would cause or contribute to an exceedance of water quality standards.

A.2.3. During the period beginning on the effective date of this permit, and lasting until the permit expires, the Permittee is authorized to:

discharge domestic wastewater, boiler blow-down water, and treated TNT water (red water) from the Process Water Treatment Facility, as described herein.

Effluent samples and measurements taken in compliance with the monitoring requirements specified below shall be taken at:

A.2.4. The discharge shall be limited and monitored by the Permittee as specified below. As applicable, exceptions to standard language in this permit are identified and authorized in the Special Approvals / Conditions table:

Notes (Discharge Limitations Table):

1. Samples shall be taken within one hour of the start of the discharge during storm events.

2. In the event that this outfall is used,the Nevada Division of Environmental Protection shall be notified during the first occurring normal business hours.

3. For each sample event, formula terms contained in A and B below shall have the following meaning: pH and T are field measurements of facility discharge taken at the same time and location as the water sample destined for the laboratory analysis of ammonia.

A. The chronic criteria of water quality with regard to the concentration of total ammonia are subject to the following:

(a) The facility discharge Monthly chronic concentration of total ammonia, in milligrams of nitrogen per liter, shall be calculated by the NAC 445A.118 Table 2 chronic concentration by value from table matrix of temperature and pH or by formula for the 30-Day average for each discharge sample event as described in NAC 445A.118.
