Your request must "reasonably describe" the records you are seeking. This means the description must be specific enough that a government employee familiar with the Public Authority's files will be able to locate the records within a reasonable amount of time and without an unreasonable amount of effort.
You don't have to explain why you want the information you are seeking - but this explanation might be necessary if you want the Public Authority to waive its fees or comply more fully with your request.
The more precise and accurate your request, the more likely you are to get a prompt and complete response
