Union Tourism Ministry on 26 April 2016 launched NOC Online Application and Processing System (NOAPS) Web Portal of National Monuments Authority. 

The Portal was developed through the technology and expertise of Indian Space Research Organization (ISRO), who are in the process of mapping of 3686 ASI protected monuments and sites.
• In the initial phase, the web portal integrates NMA’s portal with the online portal of local bodies of Delhi and Mumbai viz. NDMC, Municipal Corporation of Greater Mumbai (MCGM) and MCDs to facilitate single window clearance for construction on a common application form. 
• The applicant need to fill up a single form which will be sent to the concerned agencies by the local body, from whom No Objection Certificate (NOC) is required. 
• NMA on its part will communicate its decision to the local body within six working day, bringing down the time limit from ninety days, as prescribed in Ancient Monuments and Archaeological Sites and Remains (AMASR) Act, 1958.
• The applicant is not required to visit NMA in connection with his/her application but can track the progress of the application    online.

However, large projects involving construction of building beyond 2000 square metres have been kept out of the purview of Single Window Clearance System, keeping in view their possible impact on the Monument or the site.

Under the present rules of Ancient Monuments and Archaeological Sites and Remains (AMASR) Act, 1958, hundred meters area around the monument is a prohibited zone.While the area between 100 to 300 metres is regulated zone for which no-objection certificate is needed for construction-related works. The time limit for availing NoC was 90 days.
