renderd turn off debug logs

Is there any way to make renderd no output DEBUG level logs? There is nothing showing the man page for renderd and scanning the code doesn't show up anything obvious for log level. I've tried all the usual LogLevel options in Apache but none of them go down to the renderd daemon.

Specifically it is logs like these that I'm trying to hide

I'd prefer something in the daemon rather than having to drop these in syslog if possible.
