GRAP-1: What It Is
GRAP-1 is the initial stage of the Graded Response Action Plan, triggered when the Air Quality Index (AQI) crosses the 'poor' category. This typically
happens when the AQI readings are between 201 and 300. Under GRAP-1, several restrictions are enforced to curb pollution. One of the primary measures includes stopping construction and demolition activities at sites larger than 500 square meters. The use of diesel generator sets is also prohibited, except for essential services. Moreover, authorities may increase parking fees to discourage the use of private vehicles. Public awareness campaigns are also intensified to educate residents about pollution control measures. These actions are designed to promptly address the initial deterioration of air quality and to prevent it from escalating further.
GRAP-2: Stepping Up Efforts
When the AQI worsens, moving into the 'very poor' category (301-400), GRAP-2 comes into effect. This level involves more stringent actions than GRAP-1. Besides continuing the measures from GRAP-1, GRAP-2 mandates additional steps. Construction and demolition activities, which include all projects regardless of size, are halted entirely, except for specific government projects. The operation of brick kilns, hot mix plants, and stone crushers is banned. Further restrictions may be imposed on industrial activities, depending on the severity and specific sources of pollution. Local authorities are tasked with intensifying inspections to ensure compliance with the rules. The focus is to minimize pollution from multiple sources, aiming to swiftly improve air quality by significantly reducing particulate matter and other harmful pollutants.
GRAP-3: Revocation Explained
The recent revocation of restrictions under GRAP-3 demonstrates an improvement in Delhi-NCR's air quality. GRAP-3 is triggered when the AQI enters the 'severe' category (401-450) and includes more intensive measures like the complete shutdown of construction and demolition activities. The authorities may also ban the entry of vehicles into Delhi, except for essential services. The CAQM, having observed an improvement in air quality, rescinded the GRAP-3 restrictions. This decision indicates a welcome respite, allowing some previously suspended activities, such as construction, to resume. It also means that the overall pollution levels have decreased, reducing the stringent regulations impacting various sectors. This process showcases the dynamic nature of GRAP, designed to adapt and respond to changing air quality conditions and to protect public health.
Other GRAP Mandates
Besides the core measures outlined for each stage, GRAP-1 and GRAP-2 also include several other mandates. These may encompass stricter enforcement of existing environmental regulations, such as checking for pollution-emitting vehicles. The authorities emphasize continuous monitoring of pollution levels to proactively adapt to changing conditions. Awareness campaigns are intensified to inform citizens about the health risks associated with poor air quality, promoting the adoption of cleaner practices. These additional efforts form a comprehensive strategy for preventing and controlling air pollution. The government actively encourages public participation and strives to ensure all stakeholders cooperate to mitigate the adverse health impacts of air pollution within the Delhi-NCR region.
