For purposes of this subsection, unlawful discrimination also includes, but is not limited to:

A. The imposition or application of eligibility criteria that screen out or tend to screen out an individual with a disability or any class of individuals with disabilities from fully and equally enjoying any goods, services, facilities, privileges, advantages or accommodations, unless the criteria can be shown to be necessary for the provision of the goods, services, facilities, privileges, advantages or accommodations being offered;

B. A failure to make reasonable modifications in policies, practices or procedures, when modifications are necessary to afford the goods, services, facilities, privileges, advantages or accommodations to individuals with disabilities, unless, in the case of a private entity, the private entity can demonstrate that making the modifications would fundamentally alter the nature of the goods, services, facilities, privileges, advantages or accommodations;

C. A failure to take steps that may be necessary to ensure that no individual with a disability is excluded, denied services, segregated or otherwise treated differently than other individuals because of the absence of auxiliary aids and services, unless, in the case of a private entity, the private entity can demonstrate that taking those steps would fundamentally alter the nature of the good, service, facility, privilege, advantage or accommodation being offered or would result in an undue burden;

D. A private entity's failure to remove architectural barriers and communication barriers that are structural in nature in existing facilities and transportation barriers in existing vehicles and rail passenger cars used by an establishment for transporting individuals, not including barriers that can be removed only through the retrofitting of vehicles or rail passenger cars by the installation of a hydraulic or other lift, where the removal is readily achievable;
