He certainly had them in the past; nobody's denying that.
I don't doubt you'll find traces somewhere if you go over the right facility with a fine-toothed comb.
refusal to cooperate with arms inspectors
The last time that inspectors were in the country, they did quite well - until they were forced out. Who forced them out?
Anyway, they appear to have done a good job documenting Iraq's disarmament process on their last visit (not having been in Iraq for 12 years continuously, of course) before having to leave, and they had plenty of cooperation.
The coalition made sure to check all the sites that the inspectors mentioned, plus any likely-looking alternate sites picked out by satellite, and as yet haven't found anything. If Iraq was still working with WMDs, then it was in a separate, even-more-secret WMD programme, chinese-walled from the programme that everybody heard about, and in a hitherto undiscovered bunker complex somewhere in the desert wastes. That sounds unlikely, although I wouldn't rule it out completely
In that light, I doubt anything usable or operational will be found, or any live production facility.
