since hcv can be infectious for up to 6 weeks at room temp what is the likelihood of getting it from miniscule dried blood on an environmental surface?

None: Nobody ever gets HCV except by direct sharing of blood, mostly through injection equipment. Even sex rarely transmits it, despite what you may have learned online or elsewhere. The only proved, accepted means of sexual transmission is through potentially traumatic anal sex practices among men who have sex with men. In any case, there is never significant risk from environmental contamination.
