Hello, For the disposal of Chromic acid see https://www.chemistry.nus.edu.sg/PSSO/safety/Special%20Chemical%20Waste.htm and https://study.com/academy/lesson/chromic-acid-solution-preparation-disposal-hazards.html (more detailed).
You can precipitate the chrome as Cr(III) and store this solid for waste disposal instead of liquid chromic acid. In the process the acid is neutralized and the supernatant (of sulfates, potassium and sodium ions) diluted and washed down the sink. I hope that helps.
