UPDATE: I JUST came across this when looking for something else!
Based on the fixed and mobile output I figured it may have been DPW(public works) related, sure enough it is!
When you look at the contact on the FCC link it says "ATTN PUBLIC WORKS"
FCC Callsign WRML491 (HILLSDALE, BOROUGH OF)

I'll be monitoring for tones and submitting to the database once confirmed.
