What methods can be used to report ammonia in wastewater to the EPA?
Nitrogen ammonia methods for EPA reporting in wastewater
Nitrogen ammonia can be measured using a spectrophotometer (or colorimeter), or an ammonia ion selective electrode (ISE). Provided below are accepted or equivalent United States Environmental Protection Agency (USEPA) methods for wastewater reporting.

US ENG Nitrogen, Ammonia-Nessler Method 8038_DOC316.53.01078- USEPA accepted for wastewater analysis (distillation required), Method 350.2.
EPA Hach Method 10205, Ammonia Method-TNTplus™ 830/831/832. Spectrophotometric Measurement of Ammonia-Nitrogen and Total Kjeldahl Nitrogen (TKN) in Water and Wastewater-Equivalent
US ENG Nitrogen, Ammonia-Direct Measurement ISE Electrode, Method 10001 DOC316.53.01235 and US ENG Nitrogen, Ammonia-Known Addition ISE Method 10002, ISE Electrode_DOC316.53.01234- 

These procedures can be used for Standard Methods for the Examination of Water and Wastewater 4500-NH3 E for USEPA NPDES reporting.

As with any method used for compliance reporting, always consult with your local regulatory authority.
