Waste? Violation of 2505.4? Does not look like 50' to me.
Code of Virginia states the following:
It shall be unlawful for any person to store, dispose of, speculatively accumulate or otherwise place more than 100 waste tires on public or private property, without first having obtained a permit as required by § 10.1-1408.1 or in a manner inconsistent with any local ordinance. No person shall allow others to store, dispose of, speculatively accumulate or otherwise place on his property more than 100 waste tires, without first having obtained a permit as required by § 10.1-1408.1.
C. Any person who knowingly violates any provision of this section shall be guilty of a Class 1 misdemeanor. However, any person who knowingly violates any provision of this section and such violation involves 500 or more waste tires shall be guilty of a Class 6 felony.
